Zvidar Z-DG-Z01 (EFR32MG21) USB Zigbee Coordinator dongle manifest?

[Hedda]

FYI, here is another new Silicon Labs EFR32MG21 based Zigbee USB dongle, no more info available yet on the pins/pads used:

Apparently, it is USB discovered by VID/PID "1a86:55d4" and product USB identifier "QinHeng Electronics USB Single Serial" or with serial by-id as "_usb11a86_USB_Single_Serial54F7005713-if00" (where "54F7005713" is the serial number).

PS: I assume this is probably a clone/replica of the ZB-GW04 USB dongle or the Home Assistant SkyConnect USB adapter?
