As I'm away from the computer ATM, I cannot provide the output, but I 
ran cat /proc/interrupts, and AFAIR almost nothing was shared, I 
remember being both impressed and puzzled...

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.

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...
