How do I use this feature?
I'm trying to pass through a usb-bluetooth dongle to a Windows 8.1 guest
I have 3 Usb Redirectors in the hardware config

Ok so I figured out a workaround, though I would still like to know how to use the Redirect feature

I switched the USB controller from USB2 to USB3, because the USB2 ICH9 2935 drivers weren't working in Windows 8.1.
Then I added the dongle as a USB Host Controller. This didn't work previously in USB2 mode, but works now.
