I got a similar problem only with a adm8511 usb to lan convertor,
when I try to create a template Packet or Ndis makes no difference Norton says the oemsetup.inf file is not in a recognised format I provided norton with the original disk wich contains: net8511.inf, net8511.CAT, ADM8511.sys, AN986n.inf, release.txt
Does anybody know how to work this problem
