Just for the Parallels team, I just install VM fusion and it works. (This was after extensive troubleshooting, building new vms all of it). The problem is on the usb stack. Please make a test first. Is worse on new iMac Retina 5K. I have 5 of them with the same issue. 1 is working perfectly on 10.11.1. As soon it is updated, problem started. Check the thread! It happens to me with Philips Speechmike and Nuance PowermicII we use a ton of this enviroment for Radiologist. Is ironic because it happens on Fusion 4 and we jump to Parallels. Now is the other way around.
