Google claims the Vorke Z6 plus is the same as some Tanix box which had board pictures showing QCA9377 as the SDIO module. SDIO WiFi should probe and load automagically regardless of device-tree content, so not sure why it doesn't, but BT is serial UART based and needs the correct content in device-tree to probe and load drivers. VFD also needs content in device-tree and some detective work.
If it's a Gbit Ethernet box the Q200 device-tree should work (not Q201 which is for 10/100 boxes). I'd guess Ethernet not-working correctly is the reason for adding the USB Ethernet adaptor?
I'll think about creating something, but start with logs from Q200 dtb please. If you have the original dts or dtb file from Android that would also be useful to have.
For other boxes; start individual threads else I easily lose track of things.
