[Qemu-devel] [Bug 1587970] [NEW] QEMU Crashes when attaching USB 3.00 devices to xhci bus

[Rob Hirst]

Public bug reported:

Using qemu 2.6 with a windows7 32-bit VM, if I plug a USB 3.0 memory stick in 
to a USB 3.0 port, then pass it through to the VM via the monitor (device_add 
usb-host,bus=xhci.0,hostbus=xx,hostaddr=xx,id=stick1) then qemu asserts and 
dies - I have seen 2 different asserts one is from the xchi module - Assertion 
`intr->er_full, and one is in core.c (line 400 I IIRCC) with "Assertion 
dev->state == 3 failed"
Tried to work around by only passing in an ehci controller to the VM, but then 
if I attach a usb 3.0 memory stick to that it doesn't work in windows.
I have made sure the xhci drivers in the windows VM are up to date, latest 
version of SeaBios etc, but at the moment, I have had to disable xhci in my 
system bios and just use ehci for everything.
