I am doing some re-wiring at the studio, and one of my interfaces is USB. I am trying to figure out the longest length of USB cable I could get away with and still have robust data transfer.
The official maximum cable length for USB 2.0 is 5 meters. There's no maximum cable length for USB 3 isn't specified but 3 meters is recommended.
A powered USB hub can act as a repeater - up to 5 meters from the computer to the hub, then up to 5 meters from the hub to the device, and it's always handy to have a hub here and there.
