Brand-X Ethernet card for LC/LCII

I was given a Ethernet card for Apple LC/LCII/Colour Classic bus, but there is no way to make the Mac see it.
I've tried the Apple, Farallon, Asante and Dayna drivers, but with any positive results.
Is there anybody outside there who knows which card I was given, and who can send me the proper drivers?
A brief description:
RJ45 + BNC connectors
two leds, green and red, just next to the bnc connector
SONIC DP83932BVF chip at 25 MHz
numbers on components side:
480E P/N:05-01-0087-02
on rear side:
"MADE IN TAIWAN R.O.C." S/N 0X005654

!!! Latest news !!!
After looking in some English magazines, I've found it advertised as a CNet Technologies 480E
Unfortunately the manifacturer's FTP site carries only latest PC drivers, nothing for the Mac.
Please gimme advice if you know how/where to find such drivers.
Many Thanks!

"Sonic" are the plain vanilla chips used for Ethernet boards and they usually work with almost any driver brand. You didnt specify the system you are using (neither HW nor SW). Maybe are the drivers you have too new for the card.
Just for fun, try these old drivers (ftp.datafox.ch/pub/updates/EtherPort.hqx); there from old-old cards, but saved us many times. Maybe that in your case, they might help you too !
