** Description changed:
+ ====================================
+ SRU Justification:
+ 1. Impact: usb devices which worked with qemu previously stop working
+ 2. Development fix: a patch upstream entitled uhci: Don't queue up packets
after one with the SPD flag set fixes the problem
+ 3. Stable fix: same patch as development fix.
+ 4. Test case: you must test with certain usb devices - see below for the
exact kvm arguments to use.
+ 5. Regression potential: this patch is cherrypicked from upstream so should
be safe.
+ ====================================

Hi,
I have a "Bus 006 Device 002: ID 0d46:3003 Kobil Systems GmbH mIDentity Light
/ KAAN SIM III" (kind of smart card) in an USB port which I make available to a
Windows XP guest.
This worked fine with every older qemu-kvm version I've used so far.
But since 1.1.0 it doesn't work anymore.
The device shows up in the guest, but the software can't access it anymore
(and the guest is pretty unresponsive).
On the host I get every 2 seconds this message:
[ 7719.239528] usb 6-1: reset full-speed USB device number 2 using uhci_hcd
Command line options are:
/usr/bin/kvm
...
-device usb-host,vendorid=0x0d46,productid=0x3003,bus=usb.0,port=3
...
When I switch back to qemu-kvm 1.0.1 everything works fine again.
Any idea what the problem could be?
Thanks
Klaus
