USM3 cable length limits
Posted: Sun Apr 18, 2021 3:17 am
I have a 36 MP QHY CMOS camera with USB 3 output. My preferred route is for the camera output to go to the USB Control Hub (UCH) as it eliminates one USB cable through the mount.
Routing the camera output via a 1m USB3 cable to the UCH, then a 1m cable to a powered USB 3 hub, and finally a 5m USB extender cable to the PC does not work. The same connection on a 15 MP CMOS camera (USB3) is fine; so I assume the data rate is the issue.
If I run the 1m cable from the camera directly to the powered USB3 hub and bypass the UCH, then the 5M cable to the PC DOES work.
I thought that even USB3 was not limited in length, IF connected via a powered hub.
Is this incorrect or should I be looking in other settings or cable arrangement for a solution?
