In case of super-speed descriptors for a UVC device, the `bEndpointAddress` of the video control endpoint (interrupt endpoint), was not correctly assigned and hence it was initialized with a default value of 0x80. This caused the enumeration of a super-speed UVC device on a Windows7 host machine to fail. This patch fixes this issue and the UVC device enumeration has been tested on a Windows7 host machine.
