 Hi Gerd,

there are new assertion failed when plugging in a USB security dongle at
guest runtime.
They occur on the current GIT master  + your async patch.

/home/erik/qemu/hw/usb.c:352 usb_packet_complete: Assertion
'((&ep->queue)->tqh_first) == p' failed.
I got this only once and I'm currently not able to reproduce that.

Next one is:
Same security dongle (I tested two different hardware versions, both show
the same behaviour):
- They get detected at runtime (beside this one crash above) but it takes
quite long
- When being plugged in before guest startup I get the following assertion
- this seems to happen in BIOS before the guest OS actually boots:
/home/erik/qemu/hw/usb-uhci.c:967: uhci_fill_queue: Assertion 'ret == 2'
failed.

If you need further information, just let me know how to produce it.

Best regards,

Erik

Strange.

Might be related.  In both cases the packet queue somehow isn't in the
state we expecting it to be.

Enable tracing for these events ...

usb_packet_state_change
usb_host_req_*
usb_host_urb_*

... and try to reproduce.  Hopefully that gives a clue.

cheers,
  Gerd
