Help with a usb zigbee stick

Hi, new user here so sorry if this is in the wrong area.

I’ve got a cheapo zigbee usb stick that i can’t seem to get working.
(https://www.vesternet.com/products/zigbee-popp-zb-stick).
Zigbee compatible microcontroller EFR32MG1 inside apparently.
It shows up under hardware.
serial:

  • /dev/ttyUSB0
  • /dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0

When i add the zigbee integration it also shows up as “/dev/ttyUSB0 - USB2.0-Serial, s/n: n/a” in the drop down list. However when it comes to selecting the radio, no matter which i select (i’ve tried them all) all i see in the console is “ch341-uart ttyUSB0: failed to modem status: -110” and “usb 2-2.1: failed to send control message: -110”.

Does anyone have and ideas or advice ?

Thanks
