Seems to be something specific to your camera that we need to figure out. But if your camera is failing with the Via controllers, the Audigy controller and the TI controller, then there’s something else going on too. The Google index contains only few mentions of “isochronous cycle too long”, but that’s because kernels before 2. I have the above mentioned motherboard with the above mentioned firewire chip on it, and want to use the internal header as well as the external. A timing issue is definitely a possibility — the bulk of the latency was in the packet handling routine, which might have meant the queue function was actually able to fire back up fast enough to keep enough packets queued up. Apple wanted a licensing fee for each interface, so Intel came out with USB alternatives. Great info in this thread.

Firewire is probably considered dead nowadays as few pieces of newer equipment support it.

Asus P4PE Deluxe, Via VT firewire chipset. Only 2 devices?? – Ars Technica OpenForum
I have a Pro 40 elsewhere that I may try out, but I hate hardware going obsolete. I got something grabbed but the video was garbled with missing data so the image was scrolling slowly just like an old CRT loosing vertical sync. Going back a few years, but wasn’t the TI vt63307 identified as the one to have for Sonar and Firewire?
I used to have a Saffire Pro 40 with T. We still have to fix a permissions issue I had to increase buffers in dvgrab to to not loose frames. Regression in a new firewire-patch which isn’t in git yet.

Either Focusrite or VIA driver to blame. I guess FW interfaces are not a good investment and some of those Sapphire have been on sale. Sir Les Max Output Level: I have Firewire latency set to ‘Medium’ – ‘Short’ did not do as well for me.
Comment 25 Stefan Richter I’ve played with all the drivers from Asus oh wait, there are none for firewire Alas, my firewire devices only work when plugged into the rear port. Comment 7 Robin Theander I tried again under windows. I typically can capture for slightly longer with test-dv from libiecutils, but it usually ends up hanging as well.
