Good Evening,

I am testing our Xen 4.2 RC3 on Wheezy with the latest Kernel 3.5.2, and encountered a bug.

I am certain it is stemming from the latest kernel, since the bug is not present when using kernels 3.3.8 and 3.4.9.

I am running a Windows 7 HVM and passing USB 2.0 and USB 3.0 controllers, as well as my graphics card.

The graphics card works, and to my surprise the USB controllers are the problem.

Windows just gives me a Code 10 for all three, I tried each PCI device solo with no changes, so it wasn't a conflict, and the qemu log appears no different than with the other kernels.

Any ideas what logs I should check?  Also, is anyone aware of any changes to the 3.5.2 kernel that could cause problems with USB controllers?
