So I have a GA-p35-DS4 mboard with a Q6600, running windows7-x64. After a random crash with a bluescreen (not caused by anything particular as I recall), none of the usb-controllers are working. (And none of the devices connected to those usb ports).
All the controllers are showed up in the device manager, but every one has a warning-icon (as they are not functioning properly). The windows identifies them correctly, it shows exactly the model of each controller, and it says that the driver is installed. Now, when I try to reinstall the driver (Update driver menu item in the device manager), it tries to find it, finds the driver, but quits saying "Windows found driver software for your device but encountered an error while attempting to install it." Additionally, it displays "This operation requires an interactive window station", whatever that means...
Now get this, the same thing happens with a new pci-usb controller card! It is found (actually each time the machine starts, it is found as new hardware), but trying to install drivers leads nowhere, I am getting the same message about an interactive window station. (tried to install drivers from the acoompanying CD)
I have tried deleting those devices from device manager and let windows find them again, but that leads to same results.
Update: Now I have also tried deleting the infcache.1 file in windows/system32/driverstore directory. After a restart it was trying to find drivers for like 10 minutes (rebuilding the cachefile for sure), but in the end things got back to the problematic state. Only now the non-working controllers show up as "Universal Serial Bus (USB) Controller". i.e., not as their model names like before.
None of the ports on this extension card work either.
This should not be a hardware problem, a usb keyboard connected to the builtin usb controller works in bios, and even in another OS running the same computer (old xp installation)
What to do?
Will I have to reinstall? Can deleting infcache.1 help? Is there some way to let windows remove all old drivers and try to find all hardware again, this time only looking for drivers on a windows install disk or something?
