Re: [Xen-users] help passing USB keyboard

[jacek burghardt <jaceksburghardt@xxxxxxxxx>]

I had success passing Logitech dongle that  has mouse and keyboard attached to it. It works great. I assumed there was a limit of usb device, Did you Âunload drivers for usb card first ? Most amd motherboard have separate chip for usb 3.0 that can be assigned to domU.

I have epci usb 3.0 that is assigned to windows 8.1Â

I've also tried passing a PCIe USB adapter, but the DomU doesn't appear to want to do anything with it (devices on it become dead). ÂI can use USB passthrough of the mouse plugged into said adapter when I'm not passing the adapter itself, so I know the adapter works.

Any thoughts on which problem is likely easier to solve and how to proceed with solving it?

p.s. the domU conf is adapted from one I found for Windows 7 since there weren't many examples out there for passing VGA cards to a Linux DomU, so if there are items missing or extraneous, feel free to comment and let me know. Â:)
