[FIXED] Zigbee2mqtt can not pair

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.
