[ovirt-users] Re: Ovirt 4.3.6 USB passthrough not working with iommu_intel=on iommu=pt

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. *Jacob Green* Container Platform Engineer EMIT | APPS | Modern Apps & Platforms ExxonMobil Information Technology 1735 Hughes Landing Blvd, The Woodlands, TX 77381 | TEL:+1-832-624-4348 *From:* Don Dupuis [mailto:dondster@gmail.com] *Sent:* Friday, November 22, 2019 3:05 PM *To:* Strahil Nikolov <hunter86_bg(a)yahoo.com&gt; *Cc:* users <users(a)ovirt.org&gt; *Subject:* [ovirt-users] Re: Ovirt 4.3.6 USB passthrough not working with iommu_intel=on iommu=pt 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.
