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?

I tried everything as well.....and just gave up after my post was not replied in regards to the exact issue you have. DTM worked for my 7510 until I upgraded to a 7520 two months later......which worked for about two weeks.

When you launch DTM, check the 'COnnections Manager' and see if you can manually detect your BB. it worked for me but DTM itself would not detect my device.

It's the device. I have replaced 3 - 7780 within a year with the same problem. It's the connection between the craddle and or sync cable depending on which one you are using. While talking to Rogers in Canada they mentioned quite a few problems with 7780 and the connector pings breaking in the unit.

I had this happen with two of my 7750's. For me, I right clicked the "unknown usb device" in Device Manager and then clicked "Update driver" I pointed it to C:\Program Files\Common Files\Reasearch in Motion\ or C:\Windows\system32\drivers\rimusb.sys and my devices were re-recognized.
