Win 2000/Win XP.. this driver is a modified version of the KLSI driver (the maker of the chip in the 3Com USB Adapter), I basically, took their INF file and made it look like a 3Com adapter, all seems to work perfectly and will install as normal ( just say unzip the driver to a temp directory on your computer ).
