USB devices seemingly no long working in VM running on 6.1.3


Recommended Posts

I've had some USB devices (bluetooth keyboard, wireless mouse, wireless remote control) passed thru to my windows 8.1 VM for some time now.  Yesterday I updated to unRAID 6.1.3 (from 6.1.2).  This morning I was unable to control the VM with either the mouse or the keyboard.  This has happened occasionally in the past, it just sort of freezes up and I have to reboot the VM.  So, I did that, and after restarting the windows VM, I'm still unable to control windows with any of these devices.

 

I then connected to the VM via remote desktop and it seems the bluetooth is not enabled inside the windows VM, and I've got a yellow exclamation in device manager (I think this might be for the remote control, which hasn't worked in quite some time actually).  I see a couple of mouse  and keyboard items listed in device manager, but they appear generic, so I'm not sure if they are actually my devices.

 

So, I am wondering how I might verify if the devices are actually being passed thru to windows.  I can see the devices in the tools section of unRAID, but there doesn't seem to be anything I can find which shows what is being passed to another VM.

 

Here is the XML of the windows VM, in case it offers any clues...

Actually I'm pretty interested to see how that works out.  I haven't used Q35 in quite a while, so I'm not sure how the nec-xhci controller will work out there.  Should be fine, but honestly not sure.

 

Justin, you will need to remove the two existing USB virtual controllers in your XML:

 

    <controller type='usb' index='0' model='ich9-ehci1'>

      <alias name='usb'/>

      <address type='pci' domain='0x0000' bus='0x02' slot='0x02' function='0x7'/>

    </controller>

    <controller type='usb' index='0' model='ich9-uhci1'>

      <alias name='usb'/>

      <master startport='0'/>

      <address type='pci' domain='0x0000' bus='0x02' slot='0x02' function='0x0' multifunction='on'/>

    </controller>

 

And replace that with this:

 

    <controller type='usb' index='0' model='nec-xhci'/>

When I tried to run the VM, I got this...

 

internal error: Did not find USB device 45e:745

 

Go check the System Devices page.  Does that device show up (with a 0 in front of the 45e) in your USB devices list?  Looks like it's not attached to the system.  Maybe when you rebooted, the device lost it's connection internally somehow?
