The HoverCam USB 3.0 cable adds a new transfer mode called "SuperSpeed" (SS). A USB 3.0 cable can transmit data at up to 5 Gbits/s (625 MB/s). This is more than ten times as fast as the high speed of USB 2.0. Our standard USB 3.0 cable which comes with the Solo 8 is 4.3ft. The USB 3.0 cables were manufactured specifically for the Solo 8 and have been certified and tested with our document cameras. It is designed for situations when the PC or Mac is in the back of a classroom, and the HoverCam needs to be at the front of the classroom.
