Can you tell me where exactly to add this? Within the <hostdev mode=subsystem section? Or should I add it at the very end of the file? Thanks!   EDIT: I figured it out, this replaces the existing USB config for the device in the xml... now I'm seeing an error of zigbee-herdsman:deconz:driver no free slots. Delay sending of APS Request   Looks like I'm still unable to access the webui for zigbee2mqtt though... not sure what the deal is
