I'm having a problem with passthrough of USB storage devices to a clean install of FreeBSD10.3.
I had it working on FreeBSD10.1 a while ago on a package before pve-manager 4.1-22. (Currently on latest 4.1-33). Don't know exactly which update I had it working on since I haven't used the VM in a while.
USB Passthrough works without issues to my other Windows and Debian VMs.

Logs below when connecting any USB device. I have tried a few different brand USB drives and a usb to CF reader as well.
While the USB device is connected commands like 'gpart list' hang until the device is disconnected.
I have also tested a different USB hub and connecting direct to host usb port.

Any help is much appreciated.
 
Created a FreeBSD 9.2 VM for testing. Same problem. Connecting a USB devices causes those errors spammed and commands like "gpart show" hang until the USB device is disconnected. I'm at a loss here, nothing useful is coming up on google in regards to these errors or USB passthrough into FreeBSD.

Edit: Passing through a USB keyboard works. Problem is specifically with storage devices.
