I've found myself in a bit of a problem.

My W510 no longer have any devices for the fingerprint reader, bluetooth, mobile broadband, integrated camera (and possibly some more).

When comparing the devices in "Device Manager" to another W510, I notice that many of the missing devices are USB devices, but also that the other machine have two "Generic USB hub" and I have two "Unknown device".

When I compare the two hubs and the two unknown devices, they have the same "Location" (i.e. Port_#0001.Hub_#0001 and Port_#0001.Hub_#0002) and I guess that the missing devices (bluetooth...) are "connected" to thoose Generic USB hubs.

If I delete (uninstall) the "Unknown device" from Device Manager and reboot, I can see that Windows detects my mobile broadband device, but during the driver installation they get "device unplugged" when the driver installation for the "Unknown devices" finish.

I've tried to update the driver, but I can't find any driver for "Generic USB hub"

Anyone have a solution to this problem? I really don't want to reinstall Windows, but I might have to do it unless I find a solution to this problem...

Found the cause of the "Generic USB hub" problem in C:\Windows\INF\setupapi.dev.log.

In that file it's clear that the problem stems from the fact that usb.inf is missing...

Now I've got to figure out how to get a working usb.inf without reinstalling the whole OS
