Hello,

Reopening this issue with usb-host stalling now

ehci warning: guest updated active QH
USBDEVFS_DISCARDURB: Invalid argument
USBDEVFS_DISCARDURB: Invalid argument
husb: leaking iso urbs because of discard failure


Now with qemu-XXX-1.2.0-12.fc18.x86_64

if I have webcam open, it will stall and not resume. This is with usb-host 
directly.

Shall I enable debugging again?

Thanks,
Shawn.
