Unhappy USB Device Not Recognized

Please Login to Remove!

I used to be able to synch my 7780 via USB, but after some combination of configuration changes (including a repair to a WinXP OS install), every attempt now results in a "USB Device Not Recognized" error.

My initial thought was that it was some kind of driver problem, but it seems not so much a driver issue as a hardware ID problem. The setup log (included below) shows that the device is not being recognized as USB\VID_0fca&PID_0001 (what the RimUsb driver is looking for) but rather as USB\VID_0000&PID_000, Windows' default "usb\unknown" id. Plus the problem occurs on multiple machines, both WinXP and Win2KPro, including a co-worker's desktop that works fine with his own 7780, so I'm thinking that it's something about my device in particular and not a desktop/driver problem.

I've tried every recommended practice I've been able to find, including:
  • uninstalling and reinstalled desktop software (both 3.6 and 4.0) and drivers
  • hard resetting the device (both pinhole reset and removing battery)
  • removing the Unknown Device from the device manager and manually clearing all the old USB\VID_0000&PID_0000 ("usb\unknown") device entries from the registry
  • trying various ports, cradle vs. direct USB cable
but to no avail.

I'm stumped. Anyone else ever seen this problem? I haven't been able to find any details on the 7780's USB interface. Is there some other low-level reset command that might reset the device's PnP id?
