I just moved my OH setup to different location and removed USB hub since it really isnt needed. This caused zigbee2mqtt hub and rflink (only usb devices in use) to stop working. But if i add usb hub back, and connect rflink to it, everything works ? I have removed and ttahed it several times, allways same thing ?
USB hub has no external power. Ports are not changed during operation.
What to look and how to troubleshoot ?
