The keyboard works fine when I plug it in on my son's laptop, but so it
does when I plug it in on my desktop. It's only after some hours of
usage that it locks up, I havn't got the chance to get hold of another
PC so long. I still hope that it is some kind of software conflict
that pops up incidentally, but you're probably right that it is a
hardware problem. Would that be a replaceable device on my motherboard
? I have 8 USB 2.0 connectors of which 6 are in use and continue to
work fine (printer, PDA, camera, scanner, and GPS) when the keyboard
locks up, so I assume the USB interface is OK. But when the keyboard
doesn't work, Windows says that the (keyboard) USB device is not
recognised...
