are the usb ports on rock64 on separate bus? - shome - 09-21-2018
Are all the USB ports on the rock64 on separate bus. I dont have a rock64, else I could check using lsusb on linux.
I need to connect camera and a sensor on two different USB ports. If they are on the same bus it results to decreased or dropped frames from the camera.
If anyone operating linux on rock64 can give me the output of lsusb command, it would be helpful.
