Hi Jeremy,
I use a 15 year old Sbig camera via USB 3.0 and it works OK. Cable lengths up to 5m are Ok if you’re using a USB 2 device on a USB 2 or 3 port but be careful if you move to a USB 3 camera. It won’t work if the cable is longer than 3m or if the cable is of poor quality. I’ve had all sorts of issues with USB 3 camera and cables types and lengths at my remote observatory. (All working fine now)
