Excellent!
Is it a difference between USB2 and USB3?
Actually they all usb3.
The only difference I can tell, the usb port that works for me is “yellow” type, means always on…
So quite likely a power management issue - what is the computer you are using? And OS?
I’m with NUCi3 and ubuntu18
I had a similar issue and a 50cm usb extension worked for me.
