I think libiec61883 and libraw1394 are flexible enough to handle this. =46rom my earlier expierence with libraw1394 it should be possible. > IMO, the implementation of the kernel driver is the last resort.

I have to get my hands on some test plattforms and I need a IEEE 1394 card at home before I can really start with it :) BTW: If someone is really interested to help out, I can arrange that this persons can have a test plattform for a certain period. thanks for your enlightenments,=20 daniel ------------------------------------------------------- This SF.Net email sponsored by Black Hat Briefings & Training.
