I recently installed Knoppix on the hard-drive on a stock IBM ThinkPad 390 2626-70U. I'd like to install a PCMCIA USB card or PCMCIA USB/Fireware card on it. Some candidates are the Adaptec AUA-1420A (USB) and AUA-1422 (USB/Firewire). Also, there's a Belkin USB 2.0 and CompUSA (FMI) v2.0.

I'm looking for recommendations on a card to use that will be the most compatible/least hassle. Thank you in advance for any help you can give on this matter!
