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:

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:
