i assume you are on windows 2000
how are installing the driver
are you using the inf file provided along to install the driver ?

if yes can you reply back if this helps ?

open the .inf and add this entry

also you can use the commandline utility devcon (avl for download from ms)
to set the device capabilities i think though i have used devcon to disable some network card via commandline i am not sure and dont have access to w2k to play with this driver
