OpenELEC Template usb passthrough issues

[splnut]

I am working on consolidating my HTPC's with Openelec VM's. Everything is working fine, but I am unable to pass-through my IR receiver to my sons room (which is vital). Are there any known issues with certain usb devices? My usb keyabord/mouse work just fine. I have tried multiple usb ports (front/back) with no difference. When the VM starts the IR receiver is just black, but when I press a button the red light turns on and just stays on (instead of indicating a button press).

Try this.  Edit the VM in the XML editor. Delete any <controller type='usb'> sections. Add this:

 

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

 

See if that works.

[splnut]

Now I get this:

 

Execution error

 

internal error: early end of file from monitor: possible problem:

2015-09-01T12:35:24.166033Z qemu-system-x86_64: -device nec-usb-xhci,masterbus=usb.0,firstport=0,bus=pci.2,multifunction=on,addr=0x3: Property '.masterbus' not found

Now I get this:

 

Execution error

 

internal error: early end of file from monitor: possible problem:

2015-09-01T12:35:24.166033Z qemu-system-x86_64: -device nec-usb-xhci,masterbus=usb.0,firstport=0,bus=pci.2,multifunction=on,addr=0x3: Property '.masterbus' not found

 

Worked fine for me.  I think you probably didn't delete enough.  When you delete a <controller> section, you need to delete from the <controller part to the </controller> part (and everything in between).  From my VM, I deleted all of this (which is created by default):

 

    <controller type='usb' index='0' model='ich9-ehci1'>
      <address type='pci' domain='0x0000' bus='0x02' slot='0x03' function='0x7'/>
    </controller>
    <controller type='usb' index='0' model='ich9-uhci1'>
      <master startport='0'/>
      <address type='pci' domain='0x0000' bus='0x02' slot='0x03' function='0x0' multifunction='on'/>
    </controller>

 

And what I added in it's place was this:

 

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

 

Worked like a champ.

[splnut]

Ahhh. I got it to start the VM and will check the remote when I get home.

Ok, please do.  This is super important because if you tell me everything's golden, we will be making a change to VM manager to support this new USB controller natively in the webGui.

[splnut]

After the change, the receiver responds to button presses, but nothing is actually happening on the screen.

[jonp]

Hmm, maybe we need to see about including those drivers in OpenELEC.  So the change did result in the receiver responding, whereas before, it wouldn't respond at all.  Is that correct?

[splnut]

Yes. Before when pressing a button on the tenor the receiver would light up red and stay lit. With the new settings, the receiver lights up as buttons are pressed, but Kodi does not respond.

[jonp]

Yes. Before when pressing a button on the tenor the receiver would light up red and stay lit. With the new settings, the receiver lights up as buttons are pressed, but Kodi does not respond.

 

Have you tested this IR receiver with OpenELEC or even just Kodi in general on any other systems before?  Just curious you know for sure this IR receiver works with Kodi/OpenELEC.  If not, it doesn't mean we couldn't make it work somehow, but would at least help narrow down if we need to add something to the OpenELEC virtual disk image itself or if it's something we need to change in how we assign the device to the VM.

[splnut]

Yes. I'm currently using it with my rpi. It's worked on OpenELEC/OSMC/WMC/kodi/emby/etc.

[jonp]

Yes. I'm currently using it with my rpi. It's worked on OpenELEC/OSMC/WMC/kodi/emby/etc.

Ok, good to hear. I will confer with Eric on this and see what we can do.

Did you ever find a resolution to this? I have the same issue and have tried multiple different VM setups and the only one I can get the remote to function properly in is ESXi. My goal was GPU passthrough to my slingbox, which works great in unraid and or KVM with Fedora but to no avail the remote simply will not work the way it should.
