Hi,

Just wondering if anyone tried using a webcam with the DWC2 driver? The
webcam works great when plugged in directly to the USB port, but appears
to have alot of dropped frames when used with a HS hub.

I'll debug it of course, but just wondering if anyone has had a similar
experience?

Thanks,

Dinh
