Ok I'm starting to lose the will to live here!!
I'm trying to connect my sony ericcson K750i to my pc and everything is working fine apart from the one thing that should be working without any issues; the SE memory stick duo. Having used copious amounts of memory stick hardware in the past I know there was not an issue with my o/s config and that it recognised OEM plug and play devices and installed without problem. However, now it will not install any new USB Mass storage devices whatsoever. If they had been previously installed then they are identified and will work.
When the Hardware Wizard does it's thing it recognises that it's a Sony Erics Memory Stick but continually returns a message saying that it cannot be installed as the software cannot be found. The memory stick itself does not require additional driver software and should be recognised as a removable storage device.
I've been through various posts and have completed the following
> Installed patch in registry to prevent USB hibernation.
> Checked key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor to make sure USB storage devices are permitted; set to 3.
> Done a complete clean install of all USB devices.
> Switched PC off and unplugged to allow residual current to escape from motherboard.
> Updated usbstor.inf
> System restored.
I don't know what else to do. Personal opinion is that I must have a corrupt file somewhere which is impacting the Wizard's ability to associate the correct software to the memory stick. I believe this because the wizard knows it's a memory stick but never finds any corresponding software. Also whenever I try to update ANY driver for existing pre-installed devices it never finds software, I would normally expect it to say that the driver used is most up to date.
Any suggestions???
