Description Victor Toso 2015-11-09 08:08:44 UTC 
* This is not usbclerk bug but as we lack usbdk component here it is *

Client OS: Windws 7
Guest OS: Fedora 22
Remote-Viewer from: https://brewweb.devel.redhat.com/taskinfo?taskID=10067462

Basically you just need to have two usb webcam and then:
1.) Share Camera A with guest
2.) Disable sharing Camera A
3.) Share Cambera B with guest
4.) Disable sharing Camera B
5.) Go back to Step 1

* It took less then a minute to reproduce
