Unknown Device Problem

[shafin]

Past couple of months I used "Billionton Bluetooth Class 1 USB" and "Intel WebCam CS330 USB" in Windows XP SP2 without any problem. But few days ago I had to reinstall the Windows.

Now whenever I plug in any of these USB devices it automatically installs them as "Unknown Device"s.

I try to install the drivers thorugh "Update Driver" process with manual selection as well as automatic selection. The drivers are not recognized.

I went through REGISTRY and saw that these devices are mapped as "Unknown Device"s.

I tried to delete these values but can't succeed.

Could any one help me about how can I delete these values. I used regedit.exe

OR

How can I install a Device Driver Forcefully in Windows XP SP2.

Thanks in advance.

** I tested these devices on Win98SE in the same PC, work fine.
