Can't add Itead zigbee dongle

Itead “Zigbee 3.0 USB Dongle” is supported but it simply doesn’t show up as hardware in my Home Assistant…It’s a Silicon Labs EFR32MG21 as discussed here, but none of the usual ttyxxx addresses work and I don’t see it under Supervisor hardware.
Any suggestions?

go into the Superviser and hardware bit Isee it under the -name: ttyACM0

hope this point you down the right hole
