I am trying to install a USB keyboard on a PC that has only ever used a PS2 keyboard.
When I connect the USB keyboard nothing happens. Restart the PC with the new USB keyboard and PS2 keyboard disconnected and I get a pop up that says device driver software was not successfully installed. unknown device failed.
Device manager doesn't show section for keyboard. under USB controllers there is 1 with an "!" that says unknown device. Try and update the drivers and just says the driver software for your device is up to date - unknown device. "!" still remains.
I have spent the better part of 3 hours searching on Google for help but I have yet to come across a solution as all the threads I have looked at just end without an answer. But this does seem to be a common problem.
I ran the microsoft fix it program and it also came back with the same thing, unable to connect device all drivers up to date.
Model is a Gateway GT5426E
Windows 7 32bit
