On my 1ghz powerbook, one of the USB ports has stopped working. I plugged an external HD into it and the light on the HD blinked on and off like crazy. Not thinking anything of it, i left it, but when i later plugged in my external modem it wouldn't recognise it, same with my digital camera when i plug it in, nothing appears in the finder and it seems the things is just dead.
Is there a way to know for sure?
Cheers
