USB Keyboard does not work in ML setup

[bax2003]

USB keyboard does not work in Mountain Lion. I tried Apple ALU wired keyboard, Lotitech Media, Logitech UltraX and A4Tech one - nothing on Mac Pro 3.1.

Tried on front and back USB ports, on hub - nothing. In Lion, or Lion setup, all keyboards work fine.

***** ?

Interesting ...

The only issue I had with the ML upgrade on my early 2008 MBP was that my 3 year old Logitech mouse started acting flakey and then quit. I changed batteries, deleted the device in Bluetooth preferences and added it back in but still flakey so I went out last night and bought a new mouse. Haven't had an issue since.

It is now obvious that something is wrong with ML regarding USB on Mac Pro 3.1
