I turned on the excessive debugging output, but it didn't print out info about receiving packets or interrupts. My test app claimed there were no packets received although the bus analyzer showed lots of packets going by. If I can help out, let me know, but I'm not sure where to start at this point.

Keith, et. al, I am having problems with isochronous receives, and remembered just as I was getting ready to dig into the source that there was a message about this stuff. Lo and behold your message to linux1394-user from September 7: > I'm trying to receive isochronous streams (using libraw1394 1.2.0), and > I've noticed that if data is transmitted on channel 63, then my app tends > to work fine. If the stream is on a different channel, then I don't see > any isochronous packets at all. I'm using 2.4.29, I've also tried 2.6.15 > with similar results, can't seem to receive channels < 63. Did you ultimately have any success getting this going? Funnily enough, when I tested isochronous stuff in July, I just did iso transmit since I figured receives *must* be working since everyone has camcorders and whatnot. My currently my iso xmit stuff does appear to be working, but iso receives are not. I have a Firespy and no reason not to trust it, so I can see the junk I'm spewing out. I've tried transmitting on channels 4 and 63 (per your advice), but neither works for me. I suppose it could my stuff... nah. -- Robert Crocombe rcrocomb@gmail.com - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
