I currently have a problem with a system (vista home premium, 64bit). USB kbd/mouse will not work when windows has booted/loaded their drivers and Im stuck at the login screen with no working input devices. None of the available boot options after F8 will boot to working kbd/mouse.

They work in the bios setup and they seem powered all the way until a few seconds before the login screen. Legacy USB devices is also enabled in the bios.

They also work with the recovery dvd, but I am unable to start the device manager to check or uninstall the mouse/kbd drivers. Cant get devmgmt.msc nor devmgr.dll (with rundll32) to work.

System repair does not detect the problem and there are no available restore points (it was disabled).

Any ideas?

Do they work in safe mode? – MaQleod Oct 19 '12 at 17:26
No, no boot option with F8 works – Jonas Oct 19 '12 at 17:28
Does it work at all? Allow you into the system bios and move around for instance? – francisswest Oct 19 '12 at 17:40
This is likely a USB driver problem. Use a non-usb keyboard. – Ramhound Oct 19 '12 at 17:43
They work in bios/cmos. – Jonas Oct 19 '12 at 17:48
