Desperately need help ---> USB Devices Not Recognized!

[soapman 0]

Here is my problem. I have a Sony VAIO external 40 gig drive. It works everywhere but on my Dell Latitude D800 Windows XP SP1 Laptop. I get the "USB Device not recognized" bubble. I tried installing SP2 but when I put the drive in the laptop blue screened so I reinstalled SP1.

This thread helped my situation. I took a couple shortcuts; left the batteries in the mother board and only unplugged the power cord for twenty minutes.

 

I had originally thought my usb backup drive had gone belly-up but after three days and this thread here is my report:

 

D-Link DPH-50U

 

D-Link DPH-50U Skype AdapterAfter some time the DPH-50U reports 'Device no Present' and shows the red icon. In XP running devmgmt.msc shows 'unknown device' under Universal Serial Bus controllers. The only solution I have found was discovered here:

http://www.ntcompatible.com/Desperately_need_help_---_USB_Devices_Not_Recognized_t32356.html

 

To re-enable the DPH-50U the following steps are necessary:

 

1.) Unplug the DPH-50U from the usb port

2.) Add Remove Programs and removing the D-Link DPH-50U

3.) Start Device Manager (Run>>CMD>>devmgmt.msc) remove unknown device under Universal Serial Bus controllers

4.) Powering down and unplugging the computers main power cord for twenty minutes

5.) Boot up, re-install DPH-50U software and follow the prompts to re-plugin the DPH-50U

 

D-Link must know of this situation as it has been previously reported; I discoverd it by Googling D-Link "Device Not Recognized". While I can get it back to normal for a time it eventually goes belly-up again. Are there any solutions to this?

 

If you can think of any pm me or post here. I have a copy of my secenario here:

this topic is reeeeeeeallly old!

 

but hopefully this will still help people!

 

I HAVE THE SOLUTION! READ THIS:

 

if when you plug your ipod in it says 'usb device not recognised', here is how to solve the issue,

 

unplug your ipod from the pc

 

put you ipod into disk mode; toggle hold on and off, press and hold menu and select buttons, when the screen changes quickly press and hold select and play key, the screen should now say disk mode and have a big tick, if not keep trying.

 

now your ipod is in disk mode, plug it back into the computer, the computer will now recognise it, it may want to install an update, if it doesnt do it automatically then load the ipod updater and do it yourself, when it has installed the update it may not recognise the ipod anymore, dont worry, just unplug it and plug it back in again, it will then load for a while, when it sqays ok to dissconnect on the ipod screen unplug it and oput your ipod back into normal mode; toggle hold on then off, press and hold menu and select keys and hold for 6 seconds. plug the ipod back in and sorted! your ipod should work now

 

good luck

I'm glad it's old, and reborn

 

Okay, first post and first question.

I just purchased an XBOX360 and am trying hard to get online rosters, which are downloadable, however you need a transfer kit:

 

http://news.teamxbox.com/xbox/10383/Xbox-360-Transfer-Kit-Update/

 

- which is what is giving me the problem.I'm getting this USB device not recognized error as well. The problem occurs when I plug in the device with the memory card attached (this is what is required to be done in order to transfer data). But the device isn't even recognized when the memory card is taken out - so I believe that is the culprit. Any help is highly appreciated.

 

Specs:

 

p4 2.6ghz Sony Vaio (PCV-RS 320 Motherboard)

1GB RAM

120GB SDRAM

NVIDIA 6600GT

Someone on one of the newsgroups to which I am subscribed suggested not only closing down my computer but also switching it off at the mains socket. Seemingly this allows any residual current on the motherboard or any stray capacitance to discharge.

Believe it or not it worked! I now have all my USB ports and devices working as I want them.

Hope it works for you - it must be worth a try :-)

Oddly enough it worked for me. I still have to say WTF to whats going on.

 

My problem was my USB d-link airplus G not being recognized and windows telling me it malfunctioned (Wtf) it seems that all of a sudden USB 2.0 is not supported by the computer. I also tried a USB 2.0 hub and it still said "not recognized - malfunction ".

 

SOLUTION RECAP

 

This worked for me! thanks for posting the information! As for anyone else who has a similar problem you should try shutting down the computer and literally disconnecting the powercord from the powersupply then reconnect after a few seconds and start up the computer again! - IT WORKS!. Miraculously it worked for me!''

 

I tried this and it didnt work ,should i tried to un-install all the USB drivers first, then re-install and let it stand for 30 mins? hope someone replies as this forum is old.

 

thanks heaps!

Ok . . . here it is for those using 3.5 storage boxes with hard drive inside . . . some hard drives can function in cable mode (look at the face of the hard drive . . shows you where to put spacer/isolator) if you're having trouble, put the drive in master mode . . . it's that simple.

[apedavid 0]

I would get the "Device Not Recognized"

popup randomly, sometimes for days. Tried all the driver tricks.

 

Then discovered I would never get it with a cable under 3'.

 

Anyway I can now run a 12'cable to a device with no issues.

 

The solution was to coil the cable at the device end inside a round ferite.(just a couple loops) I think there is a high frequency issue with the speed USB2 runs at. USB one never did this under the same conditions, same cable.

 

Hope this helps somebody else.

[koolhaas 0]

I would endorse the solution - disconnecting the power altogether - I have just gone through similar traumas.

 

I have 2 usb2 outlets at the front & 4 at the back. At the back, the mouse & printer come off 2, one has a backup hard drive & the 4th is spare & is usually used for a memory stick.

 

The 2 at the front are very close together so i only use one & has i wireless stick to connect my cable modem.

 

Mysteriously, the 2 front ones stopped working, along with 2 at the back. The mouse & printer ones seemed unaffected.

 

I got the bubble message USB device not recognised as has been described in the posts above.

 

I tried various useless suggestions on the msft support forums all to no avail. The clue of course was that when my pc is shut down, the blue light is still on in the wireless stick.

 

I pulled out the power lead from the back after reading a suggestion made earlier in the thread & it was all fixed.

 

I slept well last night.

 

Thanks to one & all for the discussion .

 

cheers

This is an interesting thread, which over a 1 year span from start to now!

 

What folks don't seem to be noting is that they are trying to unplug and hot plug USB devices without removing the USB devices first from the system tray. If you remove the specific USB device from the systen tray, you should not get these messages when (hot) plugging in another device.

 

Plug in a USB device and that device occupies the specific USB port. It stays resident until you remove the device from the system tray, or shut down the computer, or in some cases unplug it.

 

Some USB devices use only the power from the system, like USB sticks. When you shut down your computer, there is still some juice to the motherboard. If your look at the motherboard's LED (if you have one) - not on the system case, but the motherboard itself, you will notice that the light is still on, indicating that there is still juice to the motherboard. This would explain why a USB stick stays lit. If you did not remove the device before shutting down (which you always should via the system tray) this happens. This also increases the risk of losing data, if you don't disengage the stick (remove it from the system tray) before physically removing it from the port.

 

Any current is usually gone after a minute or so, but on some systems, there are traces of juice still resident for some time. Hence, this is why unplugging the computer works. It totally removes any current to the motherboard and to the device.

 

USB hubs are another issue. Those with there own power source tend to work better, as they don't rely on the motherboard to power them totally. Those that rely on the system to power them tend to be less reliable and many USB devices don't like them (require self powered hubs).

 

USB 1 vs. USB 2 is another quirk. Many motherboards have both, some only the older standard. You need to consult the specs. on your particular systems. I agree that you should have the latest drivers from your motherboard company installed for proper functioning of your USB devices. This may also assure that newer USB devices may work better on older systems that don't natively support USB2, only 1. You will still get a message stating that a USB device is plugged into a USB 1 port, but they will work.

I experienced the same problem this morning...I visited several sites and had many solutions: the modify bios remedy, the disk manager remedy, the device manager remedy, the reformat remedy, the re-install windows xp remedy, the get dell service remedy....none worked. Then I stumbled on this site..google led me to you..on the third attempt -- had to use different wordings in the google query to get to different sites. Oh Bliss...it worked. But I did not wait 30 mins...just 5 and it worked.

 

Thanks for keeping this thread alive. This should go up somewhere permanent and not be buried deep in an archive. People like me spend hours and $$$ looking for a solution that is just so simple.

 

Thanks once again...best wishes to all

I tried everything shown in these posts-

 

1. Added key in registry: HKEY_LOCAL_Machine\SYSTEM\CurrentControlSet\Services\Usb

 

2. Went into device manager and reset the power option to not turn off any of the USB ports after a timeout period (had to individually do it for each one).

 

3. Pulled power cord and left it out overnight.

 

Just re-booted this morning and it still malfunctions. My Kingston Jump Drive works OK, but my new MP3 player (really a glorified Jump Drive) gets the error over and over until I pull it out.

 

This is really weird. I have three USB ports on the front of my tower and three in back and two on mother board. If I plug the Kingston into port 3 on the front, it always fails. If I plug it into port 2, it always is OK. Port 1 seems OK, too. If I then remove it from port 1 and then plug my new drive into port 1, it works there, too! But never in port 3.

 

I hope Microsoft comes up with something soon. It just recently started doing this. It works OK in my Dell laptop (both running XP Pro, SP2). Seems to be OK under Win 2000, but have had some issues with USB mouse and scanner on that machine where I had to plug them into other ports to get them to be recognized.

 

This sounds like a major problem.

 

P.S. I ALWAYS remove the USB items from the system tray before I unplug them!

 

[danleff 0]

Let me go back ro my previous comment on USB 1 vs. USB 2. Often, motherboards, depending on their vintage, have natively one or the other, USB 1or USB 2 capable on the back (attached to the motherboard) and 2 or more on the front panel. Often one set is USB 1 and the other USB 2. See your motherboard manual to check out what is on the system and where they are located.

 

The key often lies in the motherboard, either in a correct updated bios, which will handle the problem (as the motherboard company becomes aware of the issue), or updated drivers from the motherboard manufacturer.

 

So, rather than it being a real Microsoft issue, it can be a motherboard hardware issue. So ofen the solution is either;

 

1. Update the bios, if this is a known issue with hardware detection and a bios fix is needed/available to fix the problem, or, if not;

 

2. Make sure that you have the latest drivers for USB from the manufacturer's web site.

 

I would also check the motherboard's web page for any FAQ that identify the issue as known and what they recommend as a fix.

 

USB 2 ports should be backwards compatible with USB 1, but not USB 1 for 2. So if you have a USB 2 device, they malfunction on a USB 1 port, or give the system fits. This might explain why they work in 1 set and not the other.

OK, first, let me start off by saying that I've tried every solution that was possible. I cut the power for over 45 minutes and it still happens. I couldn't edit the registry because the folder names didn't match the ones posted and I didn't want to jack up my computer any more than it currently is. I deleted everything USB and re-installed it...TWICE!!! If it's on here, I've tried it. Now for the situation...

 

I bought a new HP laptop (which the estimated build date was 3 days ago and it still hasn't shipped, but you don't want me to get into that) and a printer along with it. I got the printer first, of course, and hooked it up to my desktop. Everything appeared to be working well. However, it seems that the HP software has hijacked my USB ports and will NOT let anything through. I first noticed it when I tried to plug in my iPOD nano which wouldn't be the first time one of those damn things f***** up my computer but I truly believe it's the printer. Basically, the only thing that can be recognized by USB ports. So, if anyone has any friggin clue how to undo what the evil HP has done, please let me know. I'm very computer savvy so if you happen to have a program source code or some interesting crazy s*** to try, I'll do it. I really wish that everything would work but if I can't get this fixed, I'm not buying HP anymore and everything ordered will go back cause it doesn't work.

i am also seeint the same thing with my 1 gig usb pen drive n it doesnt workon any body computer.my question is > can the metod posted fix my device

[wooly 0]

i have a 1gig pen drive when i try useing it I got an error: "USB Device not Recognized. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it."on my computer, so i try another computer got the same error message.can this link fix it

http://support.microsoft.com/default.aspx?scid=kb;en-us;817900 let me know plzz

Yes, "cord off for 30 minutes" means leave the cord off/batteries out for 30 minutes. I've seen people complain that when they clear their CMOS it doesn't fix anything. They pull the battery/move the jumper, but don't unplug from the wall. See the wee LED's on the mobo all lit up? That's power going to the mobo.

 

Turn off all power, pull all cords, allow the system to sit that way for 30 minutes, then power back up.

I couldn't agree more. I have encountered this problem more than once on many systems.

I have never found away around the problem you describe other than to re-install the windows software from scratch.

I now have a friend who has this problem, but he doesn't want to reinstall the operating system.

If anyone has a solution to this, please let me and 'HP Sucks' know.

I would like to jump in here and say I have had the same problem, however, I am using a HP Pavilion DV4 1028us and I started to receive the same message my USB ports were not being recognized. I did follow one post on here about the registry change.

 

"Run regedt32.exe and navigate to;

 

HKEY_LOCAL_Machine\SYSTEM\CurrentControlSet\Services\Usb

 

Create the Usb key if it doesn't already exist. Under this key, create a new DWORD value called DisableSelectiveSuspend and give it a value of 1. Then restart the PC."

 

After I restarted my computer that didn't solve my problem though. I ran into this problem several time with this particular machine and found that when this starts happening I first shut my computer down and remove the battery. I then restart and remove all USB device under device manager and then shut my computer down. I then restart it with the battery plugged back in but not plugged into the wall jack. After that I let the machine find all the USB components and for some reason the USB ports start working again.

 

I'm not sure if this will work for any one else but it did solve my problem.

I have an internet cafe and so far no problems with clients plugging usb's and phones in to upload photos to facebook etc untill one client brought in a Nokia phone like every other don't remember exact model. We could not get it to open. After giving up no one else could plug any USB into three of my ports.My printers work and speakers etc. Also got the message USB Device Not Recognised. Googled for 1 week untill I finally found this thread. So I followed the instructions of unplugging my computer from the wall and I waited about 10min. After I switched everything on VOILA my USB and everyone elses is working once again. Under "My Documents" is a Folder called My Drivers. In that folder I found another folder called "Details" then another one called "USB" then "USB Unknown". In that folder are 4 documents the one says USB setup information and it is about 10 pages long stating all the information about the Noikia Phone I was trying to install.

It does state that "This file contains usb descriptions of USB Hubs and composite devices. I think that these filders are on my PC because I use "DriverMax" and "Driver Detective" so one of them must have put that "My Drivers" folder on my PC which has helped. I am very happy to have solved my problem. Thank you very much. I WAS LOSING MY MIND. Now I am a happy googler.

I face the same problem. My computer is Sony Vaio laptop with Windows XP.

I connect printer, scnner and mouse via USB port. printer and scanner worked fine. I added mouse few days ago. Even mouse worked fine until today. Today all of a sudden mouse didn't work and the error message pops up every few seconds.

 

I tried to use the method explained in below thread. I find out that there are many usb related subdivision on left pane. They are: usbccgp, usbehci, usbhub, usbprint, usbscan, usbstor, usbuhci, usbvideo,

 

Which folder should I use to create the mentioned key?

 

PS) Error message appears even after plug out of all usb ports

 

Looking for your reply.

Yabi

 

Thanks for the info.

 

It seems that many people are still getting the 'USB Device not Recognized' problem from time to time. Unfortunately there is no easy fix.

 

Firstly, it's recommended that you make sure every one of your motherboard drivers are completely up-to-date, but you probably already knew that.

 

In XP, after a USB port isn't used for a long while the USB driver built into the OS sets the OHCI controller to suspend. When you plug a device back in, it can sometimes fail to 'wake up' properly. This problem was supposedly fixed in SP1 but there is a related registry hack that may still be able to help.

 

Run regedt32.exe and navigate to;

 

<span style="font-style: italic">HKEY_LOCAL_MachineSYSTEMCurrentControlSetServicesUsb</span>

 

Create the <span style="font-style: italic">Usb</span> key if it doesn't already exist. Under this key, create a new DWORD value called <span style="font-style: italic">DisableSelectiveSuspend</span> and give it a value of 1. Then restart the PC.

 

A long shot perhaps, but I recall having similar problems with a USB hub built into my Microsoft keyboard and adding this key seemed to solve it. It wouldn't hurt in trying <img src="public/style_emoticons/default/smile.gif" alt="smile" title="smile" height="15" width="15" />.

 

Alternatively, removing all entries relating to USB in Device Manager and all associated USB drivers will force XP into refreshing the USB driver stack.

 

Begin by unplugging all USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software. Next, boot up into safe mode and go to Device Manager. Once in device manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this order;

 

1. <span style="font-style: italic">USB peripheral devices</span> (printers etc.)

 

2. <span style="font-style: italic">HID and/or Composite USB (Human Interface Devices)</span> You're using PS/2 input devices so you may not have this entry.

 

3. <span style="font-style: italic">USB Root Hub(s)</span>

 

4. <span style="font-style: italic">USB Host Controller(s) (Universal or Enhanced Host Controllers)</span>

 

Then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Proceed to plug your USB devices back in, starting with your powered hub. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in.

 

Hopefully some of this may be of help, let us know how you get on.
