Ok, thanks - this was doing the trick!
Looks good - it seems it's basically working. Not much detailed testing so far, but it passes test15. You said it should work for ISO-OUT, so I assume the ENOMEM-failure of test16 is within expectations?
Yes, especially if it goes with a KERN_DEBUG message saying there are no ISO-IN splits yet. It's essentially all coded, but microframe scheduling needs tweaks for the IN cases. I decided to force ENOMEM until that code is ready ... someone willing to play with the code could turn it on and shouldn't find it needs many changes.
I had some debugging on the ezusb, so at least I know it was actually receiving the iso-out data with correct crc. But I haven't checked for synchronisation and data correctness.
How would you test for ISO synchronization?

Feel like using an "official" ID, by the way? I have a few IDs left I can hand out ...

Ah ... sneaky config! Does it work with MaxPS 1023, or with bigger intervals? The split transaction support needs to use a sixth microframe for transfers larger than about 940 bytes. I can't currently test those at 1 msec intervals.

Does "-g 32" work too? If there were issues there I'd expect them to be with "test 10".

That's handy: control out testing makes "usbtest" cover a lot more of the basic host and device functionality.
/proc/bus/usb/001/004 test 15, 8.008405 secs /proc/bus/usb/001/004 test 16 --> 12 (error 12)
Where presumably OHCI worked just fine; and UHCI, which I rarely test.
