Maybe the ps/2 port and serial/parallel ports also don't work? Lots of people use USB for human inputs, and few people use serial/parallel ports, so I wouldn't expect OP to have tested those ports.

They probably work on most boards, just like the PWM probably works on most boards. But his board seems to have a broken trace or a faulty chip.

Your hunch is correct, I did not test the PS/2, serial or parallel ports, and I'm only using USB.

Might be worth trying the ps/2 port, if you've got something that fits it.

Or loopback on the serial port; just have to enable it in BIOS, don't need a connector or a serial device.

[bobsterlobster]

Will do. Might be worth to look into it a little deeper.

Bios would error out after not being able to initialize PS2 controller.
