Some PCI Firewire and Cardbus Cards work just fine with the MOTU 828. However, MOTU has discovered some problems in Firewire cards that use NEC type chips. We've specifically found problems using Orange Micro and Western Digital cards. We
recommend cards that use Texas Instrument or Lucent chips. Specific cards that we have tested an okayed are Keyspan & ADS Pyro (uses TI) and Sonnet Tango (uses Lucent). Check with your card or cardbus vendor on chip type before purchasing a Firewire card for use with 828.
