The USB 2.0 via PCMCIA card continues. My search was not in vain. :-) Just for the record: I bought now a "2 Port USB 2.0 CardBus" card from Transcend. And the ehci/ohci driver compiled into the kernel recognized the card imediately (running a custom compiled 2.6.14.3 kernel). There seems to be no problems at all. :-) Thanks Justin for your encouraging message! :-) - Martin
