More info?)
I did that. I tried all the other tips suggested by other members here. I
removed ALL USB devices, plugged them back in, etc. No help. Everything I
seem to read, including documentation that comes with the hardware is that
no drivers are needed. They are included with WinXP.
This really appears to be a Plug-N-Play issue with recognizing USB devices.
Thanks for your suggestion anyway.
