PCMCIA-Ethernetcard 3Com Typ 3C589D for Jornada 720

I have a problem with a 3Com Network-PCMCIA-card type 3C589D.

I loaded the last concretes Driver for Windows CE 3.0 of this forum here and also successfully installed. After the Softreset, I input then the Driver Name 3c589.dll and with "ok". After ca. Also the green Lamp, the Jornada 720 illuminates reacts 5 seconds however then no longer. I made that now repeatedly with always the same result. Lies it at the driver?, gives it another other driver for this card for Windows CE 3.0? On the 3Com-Homepage, only drivers are tried for this card, for Windows CE 2.11, that I also, go that however not. Can someone help me? thanks.

Have you tried existing troubleshooting steps:

There is no point me repeating what I've said several times before.
