February 1, 201511 yr So i have the device (hauppauge 955q) passed to the windows VM with "usbdevice = ['tablet', 'host:2.3', 'host:2040:b123']" in my windows.cfg file This is based off the unraid machine spitting out root@Icarus:~# lsusb Bus 001 Device 004: ID 2040:b123 Hauppauge Bus 001 Device 005: ID 14dd:0002 Raritan Computer, Inc. Bus 001 Device 002: ID 0781:5567 SanDisk Corp. Cruzer Blade Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 002: ID 0764:0501 Cyber Power System, Inc. CP1500 AVR UPS Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub However windows will only show it up as a composite device and not allow me to install the drivers to use the usb tv tuner. Any thoughts?
February 5, 201511 yr Have you tried it as; "usbdevice = ['host:2040:b123']" I wouldn't generally have the first two items in any of my passthrough lists. Apart from that, the fact that you're seeing a device in Windows would cause me to think that it might not work and that composite device is all you're going to get. What version of windows and do you have?
February 6, 201511 yr Author Meep! thank you for the reply. I have not tried just "usbdevice = ['host:2040:b123']" yet i will give that a go. I didnt think it would matter as windows8 is seeing the device. I did read that usb pass-through does not like "complex" devices...
February 6, 201511 yr You could try passing through the entire usb controller as a pci device. I had trouble with some usb speakers using usb passthrough but when I connected them to a port on a controller that was passed to the same vm, the issues went away.
February 7, 201511 yr Author True however this is connected to a USB port on the MOBO.

I have 2 USB ports on the back plate and a USB jumper connected to the USB headers on the MOBO.
February 7, 201511 yr Unfortunately, it looks like you have only one USB controller so passing it through will prevent access to all your USB ports (including the one you use for unRAID boot) so that's not an option :-(. If you var a spare PCI or PCIe slot, you could adda USB expansion card, pass that through and connect your external device to that. Otherwise, I think you might be stuck. Sorry
February 7, 201511 yr In Xen, USB devices can be passed through by bus or device. The advantage to device passthrough is that Xen will find the device no matter what USB port it is plugged into. If you pass through by bus, the device is expected to be at that bus address and the bus address for the device might change on reboot. I could not get a mouse or keyboard passed through by bus, I had to pass them through by device. It may be that the TV Tuner is happier being passed through by bus.
