Hello Atte,
Maybe the USB host controller shares its interrupt with the GPU? Could
you post the output of *cat /proc/interrupts* ? And what JACK settings
are you using?
Don't remember the exact settings, but priority round 65 or 85,
frames/period 128 (even very problematic at 256), periods/buffer at 3,
samplerate 48000.
And did you try different USB ports, different USB
cables?
I thought about that but didn't get around to trying that. I think it
has 4 usb ports + it sits in a docking station with additional 2-3
ports. I *should* make no difference according to my logic, but my logic
has failed before, so...
The cable was the same I used on my box, where performance was great...
