Hi Gerd,

I'm getting

qemu/hw/usb/core.c:410: usb_packet_complete: Assertion 
`((&ep->queue)->tqh_first) == p' failed.

with a passed-through USB headset (UHCI controller). This was with
current QEMU git head. Known issues? Anything I can do to debug it?

Hi all,

I get this with another USB 1.1 hardware (running via UHCI) as well. Some weeks ago it was fine. @Jan: If you go back some weeks, this should work (begin of April was definitvely ok). How long does it take to get the headset fully detected in your guest so that you can use the hardware? My USB 1.1 HW takes ~ 60 seconds to work, after that everything is fine - during that I see several USB resets on the host (dmesg).

Best regards,

Erik
