Hi, I am trying to passthrough a USB device via VM but could not get anything to work.

 

This is what I see if I run lsusb

lsusb
Bus 002 Device 004: ID 0781:5567 SanDisk Corp. Cruzer Blade
Bus 002 Device 003: ID 0764:0501 Cyber Power System, Inc. CP1500 AVR UPS
Bus 002 Device 002: ID 8087:8000 Intel Corp.
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 011: ID 1852:7022 GYROCOM C&C Co., LTD
Bus 001 Device 010: ID 1a40:0101 Terminus Technology Inc. Hub
Bus 001 Device 002: ID 8087:8008 Intel Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

 

I understand the unraid flash drive is in Bus 002. I am trying to passthrough the port containing the "Gyrocom" device which is Bus 001.

 

My IOMMU settings in Info tab shows "disabled".

 

The VM in unraid can "see" the usb device that i want to passthrough but although it can see it, the usb device is not functional.

 

Question is am I able to passthrough a usb port if I buy an external PCI usb card? If so, which chipset should I go for maximum compatibility.

 

Thanks

Since you have iommu disabled, it will not help to buy a new card. You need iommu enabled to pass through PCI cards.

Did you install the drivers for your device in the VM?

Thanks for reply. I could not have IOMMU enabled. I think it is the limitation of my current hardware. I have a Asrock H81M-HDS motherboard with a Celeron G1840. 

 

HVM says Enabled however.

 

Any way I can get USB passthrough or is it a dead end on this hardware.

It all depends on the device I think. You could try to change the USB mode in the VM template and see if that changes anything.

Thanks. I did not install any usb drives as the operating system in the VM is actually linux based. It is Daphile media server. www.daphile.com

 

I have tried in VM EHCI and XCHI still not helping.

Try another OS/distro as it might be related to Daphile.

Good thought. I will install a windows VM and try to see if there is an issue with usb passthrough.

Hi again. So I now install windows 10 in a VM and it recognize the USB DAC that I am connected. But there is no signal coming out of the DAC still so I think unraid docker is preventing the usb from passing through even though the docker vm can see the usb device.

 

Any ideas?

That didn't make much sense to me. Docker and VM are two different systems. 

If changing the USB mode in the template didn't work, I have no other suggestions for you.

sorry i didnt say that right.

 

I am indeed referring to the VM and not the docker.
