Hi,
I've been trying to set up a windows 7 virtual machine to do vga
passthrough, using the q35 machine as a base. The setup seems to be working
nice except than, when removing the emulated vga, libusb drops the usb devices
with an error close to this:
qemu-system-x86_64: libus
Public bug reported:
I'm trying to setup a q35 vm with windows 7 guest for vga passthrough.
The machine works well for this purpose, but the usb devices passed to
the vm does not. I receive the following errors on screen:
qemu-system-x86_64: libusb_release_interface: -4 [NO_DEVICE]
libusb: error
Narrowing this down, I launched the vm passing the usb devices one by
one. I boot correctly with the game pad and the mouse. For any strange
reason the keyboard is the faulty device with q35. The model is the
following:
Bus 004 Device 002: ID 03f0:0024 Hewlett-Packard KU-0316 Keyboard.
It's a bit
Actually moving the device to some other port made it work, so then the
suspicious is not the keyboard, but the controller where it's unplugged,
which is the following one:
00:12.0 USB controller: Advanced Micro Devices, Inc. [AMD] FCH USB OHCI
Controller (rev 11).
** Summary changed:
- Usb pa
Finally, I tried several combination of ports for this, until I figure
out and arrangement that worked for me. Seems like the problem is that 2
hp usb devices cannot share the same bus, so no matter if it's using an
ohci controller, an ehci, controller, or even xhci, if the devices are
in the same
Hi,
Adding qemu-devel.
Best regards.
José.
