Subject: [Qemu-devel] [Bug 1587970] [NEW] QEMU Crashes when attaching USB 3.00 devices to xhci bus
Date: Wed, 01 Jun 2016 16:02:00 -0000 [thread overview]
Message-ID: <20160601160200.996.35165.malonedeb@wampee.canonical.com> (raw)
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.
