Hi,
Might be a bug in the XHCI controller driver or XHCI HW, that the
isochronous transactions don't get scheduling time.
Do you have the possibility to test on another computer running FreeBSD?
There is a debug knob for the XHCI controller,
sysctl hw.usb.xhci.debug
Try flipping it to 17 for a second while in the "timeout" state, and
then flip it back to 0. Prints end up in dmesg and /var/log/messages .
It might sched some more details into the exact XHCI error code.
