May 21, 201610 yr I am still struggling how to get USB devices working from the VM (Win10). I have connected an external HD via USB. I can hear that the USB port is working as the HD is spinning and a light turns on. Unfortunately, VM settings show "USB devices: non available". Log below. Any thoughts and advice appreciated. Thanks in advance! tower-diagnostics-20160521-1207.zip
May 21, 201610 yr You are not giving too much info about your setup but as far as I know to have hot plug and play support on USB you need to passthrough the entire controller, otherwise I think you need to have the disk connected before you fire up the VM
May 22, 201610 yr Author Thanks for your reply. My issue goes beyond hot swapping. Even upon restarting Unraid or restarting the VM, it does not show any USB devices. I may be missing something very obvious and there may be an easy fix to my problem. Let me elaborate what I am doing: I stop the VM and then go into the VM settings. Then I go to "advanced", where I expected to be able to activate USB devices. Unfortunately, under USB devices, it just says "non available". Any idea what could be driving this? Or am I missing anythign / doing anything wrong? Thanks in advance for your help!
May 22, 201610 yr Author Thanks! Not sure. Please see below. Not sure whether one of this is my harddisk attached to USB? root@Tower:~# lsusb Bus 002 Device 002: ID 8087:0024 Intel Corp.

May 22, 201610 yr Umm hard to say but maybe if you unplug it and run lsusb again could help to identify it!
May 22, 201610 yr Author Great idea. After unplugging it, ti shows the same. So, it appears that it is not being recognized at all. Any idea why?
May 22, 201610 yr I'm not familiar with unRAID yet but it might be because the disk cannot be mounted for some reason. Have you tried using the Unnasigned disk plugin (or similar name, sorry I'm on my phone). I think it's used to mount/unmount drives separately from the array and maybe it could help or give more light about the problem
May 22, 201610 yr Author Thanks. This indeed (sortof) provides the solution. I can mount the disk with the plugin and then access the disk via SMB share on Unraid. This is not the ideal solution as it would be much nicer to access the disk directly from the VM. I believe USB passthrough had been quite experimental so far and there were quite a few changes expected for the upcoming 6.2.0. So, probably worth to just wait for now?
May 22, 201610 yr Take a look at the wiki or the KVM forum, there's a lot of threads for USB pass through! Maybe with the disk mounted there's an easier way to find its bus and add it to the VM
May 22, 201610 yr Author I think it is the same issue as I had mentioned in another thread. It may be fixed for 6.2 or maybe a later release version. For now, now USB for me, but can do the work-around. Below the thread I am referring with an upcoming fix in either 6.2 or a later release. http://lime-technology.com/forum/index.php?topic=42368.msg402954#msg402954
