Is it possible to run ADB on multiple devices using Hyper-V? What I would like to do is use Hyper-V to set up N number of VM's, each one being used to run a different set of tests on a different Android device. It seems like Hyper-V doesn't accept the input of the USB device. 

My question is: Is it possible to run ADB on multiple devices using Hyper-V? If so, how?
See the USB access from guest in Hyper-V question on ServerFault — in short, Hyper-V does not provide any way to access host USB ports from guests. There are some workarounds — mostly “USB over Ethernet” solutions.

Another option which could work for some use cases is to enable Wireless ADB on the devices, and then access them via the network.
