[Qemu-devel] EHCI USB regression in 1.2.0 - ehci_state_fetchqtd() asserting

[Shawn Starr]

Hello QMU folks,

The latest EHCI patches and or USB redirection ones have caused a regression. 
Using the (legacy) qemu-kvm git master repository which does 
not have these patches (not sure which patch is causing assert specifically 
yet). Using a Logitech QuickCam Pro 9000 and starting  a Windows VM 
will crash when the device is detected.

Crash in log:

qemu-kvm: /builddir/build/BUILD/qemu-kvm-1.2.0/hw/usb/hcd-ehci.c:2018: 
ehci_state_fetchqtd: Assertion `0' failed.
2012-09-19 15:36:04.011+0000: shutting down

I only came to this conclusion after noticing at least in Fedora that 1.2.0-rc1 
did not have any of the EHCI and USB redirection patches added. So by using the 
-rc1 spec 
file w/o the patches I can use Qemu/KVM successfully w/ webcam and no asserts.

I have also installed:  usbredir-0.5-1.fc18.x86_64

Thanks,
Shawn.
