Hi all: I've plugged a Cuecat (bar scan reader) into the USB port via the Ratshack PS2 --> USB converter. When the computer reboots the error message cited above is displayed. When I click OK, it logs me in. I go to device manager and look through properties of HID devices and XP claims all is working properly. I installed Catnip rather than the software that comes with Cuecat. Does anyone know what is causing this error or how to get rid of it? XP settings issue or device/driver issue?
