Zigbee USB dongle connected again - AlexLV - 03.07.2026
Hi,
for some tests I connected back to LM USB Zigbee stick E18-2G4U04B to LM USB port. Zigbee config I switched to USB. But not working, at used ports USB stick not seen. Do I need to do some usb port setting/reinitialization? Previously modem was connected to USB port. Will it work with latest FW of LM? Actively stick was used ~ 4 years ago. Can I also use USB HUB?
Init script:
os.execute('echo 1 > /sys/bus/platform/devices/ci_hdrc.0/force_full_speed')
os.execute('echo 1 > /sys/bus/platform/devices/ci_hdrc.1/force_full_speed')
os.execute('usbreset /dev/bus/usb/001/001')
BR,
Alex

Post what you have in System config > Status > System log when the dongle is connected to LM.

Enable debug logging in the ZigBee app configuration and post what you have in the ZigBee app logs.

Finally USB Zigbee started after 3rd reboot, may be USB Hub not seen previously
