Problem with USB passthrough and Windows 7

Problem with USB passthrough and Windows 7

[Joshua J. Kugler]

I am having trouble with USB passthrough and a Windows 7 guest.

It may have to do with this bug, which I am not sure is still valid or not:

https://bugs.launchpad.net/qemu/+bug/685096

I am trying to get USB devices to show up in a Windows 7 box, and have had no 
success.  My full command line is here:

https://gist.github.com/jkugler/1c47ff0f34ac46a156f6b69abd1b66d9

I have all the USB hubs/ports listed in there as far as I know.  I have this 
too: "-device usb-host,hostbus=2,hostaddr=5,id=hostdev0" which is the actual 
device I want to pass through.  But  it is not showing up in Windows 7, and 
usbdevview is not showing it as connected either.  I did notice this in the 
command line; not sure if that has any affect: "-machine pc-i440fx-
xenial,accel=kvm,usb=off"

I used the method described here: http://www.linux-kvm.org/page/
USB_Host_Device_Assigned_to_Guest ("Managed, using virt-manager")

Any ideas?
