I'm trying to use a Logitech Unifying Receiver for pass through to a Linux VM.

 

It works most of them time but occasionally stops working and disappears from the available USB devices. Restarting the VM does not help and the other VMs no longer show it as an option. Rebooting the unRAID server solves the issue for a while.

 

Is there a less intrusive way to get the VM module to see the USB again without bring down the server?

 

Thanks.

You could always try passing through the USB controller if nobody has a better idea.  That does mean that anything else on the same controller gets passed through so make sure it doesn't have your unRAID boot flash drive attached before attempting to pass through the controller.  I would consider this a brute force last try approach unless no other ideas are suggested.

 

Another thought I just had: Powered hub.
