I’m having an issue with powering multiple devices from a usb 3.0 un-powered hub. I have connected an Arduino Mega, an Arduino Nano, an action camera (used as webcam) and a Scanse Sweep lidar. When evertyhing tested seperately everything works flawlesly (so no coding problem I assume). When trying to use simultaneously unespected crashes occur randomly.
I assume that it has do to with power issues from the usb 3.0 port on my tx2 because lidar stops rotating and restarts, and when used on the seperate usb port (with the little white adaptor) it doesn’t happen.
What I’d like to ask, first of all, is this possible to happen, or do I have to look for my problem somewhere else? And secondly how I’m I gonna solve this? Is a powered hub the solution? Has anyone tried something similar or has a tested powered hub to propose?
Lastly, it will be helpful if someone can tell me maximum current draw from usb 3.0 port and usb 2.0 port for my Jetson TX2 Dev Kit.
