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).
