The previous wireless keyboard / mouse combo could conflict with the
newer USB keyboard. If the Trust keyboard / mouse had their own
enhanced drivers installed should be uninstalled.

Thanks for your input.
There were no enhanced drivers for the Trust combo. It was a case of
plugging the receiver in and letting Windows do the rest. I must admit I'm
stumped how installing a USB keyboard can be so difficult when I've
uninstalled the Trust combo.
