Thinkwiki says its got a QM67. That does USB 1.1 via the "Rate

I guess linux's hub driver is the culprit.

i've been running AVLinux5.0.3 on a ThinkPad
T61p for a while now....
with an ART USB Dual Tube Pre, i can run Jack at 64 frames, 2 periods
now i've got a new ThinkPad T520, and if i start jack on USB at 64*2
i get hundreds of xruns in seconds.
Both machines run (I assume) the same software? Then the problem is
with the hardware, or its drivers.
Please show the output of lspci and the contents of /proc/interrupts.
