U have an usb ethernet adaptor for my laptop and it worked fine under win 98, i just upgraded to win xp, and it does not work, it will log onto the net temprarly but then will crash - switch off and baclk on again. I am unable to install it from its original disc also. Are there any drivers i can use to make it run on xp or sholud i go back to 98?

also meant to say its made by Psion, it plugs into the usb port and allows me to use cable, but since updating to xp, i can't reinstall it! It works for a few seconds on the net- then goes very breifly to a warning screen about the wrong drivers without giving me time to read it b4 shutting down and restarting. Where can i find a driver for this device to allow it to work on xp!
