I have Backtrack hosted on a Hyper-V virtual machine, and I want to give it access to my USB WiFi dongle, not just access to the network, but actually access to the hardware itself so I can scan for WiFi networks etc.

In the past I have used VirtualBox, and this has been relatively painless, but I have Windows 8.1 Pro, so thought I would give Hyper-V a go.

With the device enabled under "Network Connections" I the following error:

Failed while adding virtual Ethernet switch connections. The Requested resource is in use.

Enabled

When it's disabled, I get this error instead:

Failed while adding virtual Ethernet switch connections. Adapter not enabled or not functional.

Disabled

Is this possible, or do I need to head back to VirtualBox?

Why are you messing around in the Virtual Switch manager if you want to attach a USB device to your VM? –  Michael Hampton Oct 20 '13 at 17:12
    
@MichaelHampton This is my first time using Hyper-V, what should I be messing around with to attach a USB device? And to answer your question, I thought you may be able to expose the WiFi hardware directly to the VM, regardless of whether it was USB/PCI etc –  JMK Oct 20 '13 at 17:24
    
Oh... a simple Google search turned up the fact that Hyper-V doesn't support attaching USB devices directly to virtual machines at all. –  Michael Hampton Oct 20 '13 at 17:28
    
Really? I'm seeing lots of stuff about Enhanced Session Mode which apparantly is for exactly this. –  JMK Oct 20 '13 at 17:37

Hyper-V does not support USB redirection. VMWare ESXi does from v4.1.

I personally needed USB redirection and had to use a commercial USB redirection software USB Over Network. This software works by redirecting the USB connection from the host machine (Windows 8.1) to the client (VM) over TCP/IP
