configure USB on the virtual machine
I receive the following error msg:

				Hi Seb!
I'm guessing from some of your previous posts that you're running the VM on Windows..? If so, could it simply be a matter that Windows has taken over the Crazyradio and did not release it to the VM? I'm not entirely sure how this works on Windows (I'm a Mac user) but I know on Mac it can cause a problem with VMs getting access to devices.
I also found 
this thread (a little old though) on the VirtualBox forum. It has some suggestions - you might have already seen it.
Probably not much help, I know.

				Hi thanks it may be 

 I will check it out and try to find out the solution. For sure it worked for me when I have used client installed in the Win7. I dont know maybe the cause is Win10 I have now.

				It seems it works now in the best way and I didn't have to do anything, like VM automaticaly found drivers and installed them. Crazyradio was just switched on when first I started VM and then unplugged and plugged again Crazyradio.
Thats all

				I'm having this same problem.  My VM cannot find my USB devices even though I have the Xbox Controller and CrazyRadio PA attached.  My VM reports "No USB Devices Attached" and when I try to attach them I get the same "busy" error.
Is there anything I can do?
