Have you tried making sure it is plugged into a USB 2.0 port or hub? I have had no luck passing through USB3.0 in the past.

Actually this is broken on an earlier version of ovirt at another customer of mine. They are running ovirt 4.2.3. I tried to make sure I could get it working on the latest release in order to troubleshoot that issue. I have provided the latest information and created the bugzilla case.

Have you checked if the issue is specific to this host ?

Also , check on another VM.

I would recommend you to "unpresent" that USB, then replug (if that's possible) the USB and then to refresh the hosts's Capabilities (management dropdown). Only then try to assign the USB.

I am trying to pass through a USB Dongle to a Windows virtual machine in ovirt 4.3.6. This will work if these options aren't used. Below is the output of lsusb with no iommu enable:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Bus 001 Device 005: ID 1604:10c0 Tascam

Bus 001 Device 004: ID 1604:10c0 Tascam

Bus 001 Device 003: ID 1604:10c0 Tascam

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The device I am passing through is Bus 001 Device 002.

This is the error I get in vdsmd.log:

qemu is qemu-img-ev-2.12.0-33.1.el7.x86_64

Any help with this issue would be appreciated.

Thanks
