GC USB controller adaptor + 8BitDo Retro Receiver = nothing?

[lightwo]

Even though there are very few games that benefit from or make use of GameCube controllers on Wii U/Switch, I was surprised to find that if the 8BitDo Retro Receiver (Bluetooth adaptor) was daisy-chained with a third-party GameCube USB controller adaptor (WUP-028 clone), it simply wouldn't work.

Power doesn't appear to be an issue because the adaptor blinks and even connects to a compatible controller, but inputs simply don't get registered no matter what port the adaptor was plugged into.

Is this also the case with a genuine WUP-028 USB controller adaptor? Is it merely an issue with the 8BitDo Bluetooth adaptor? It is a bummer that I can't use my modded wireless GameCube controller (or any other compatible controller) in cases where the 8BitDo Bluetooth adaptor's USB connection doesn't work, and I'd also like to update my article on the mod kit and adaptor.

For reference, here's an image of 8BitDo Retro Receiver:

For me I have the 8bitdo Ultimate 2 Wireless, it works with Bluetooth for PC, with the wireless USB C adapter, or with the USB C Cable plugged into the device.

I've tried many adapters, all of them the wireless adapter and controller connect, no inputs detected. Afaik it's an issue with the switch using a wireless adapter through any other adapters or hubs. I have several USB C hubs with HDMI, and USB C for data, and for power, essentially a dock. None of these adapters enabled my 8bitdo controller to work through the adapter.

Can you please clarify your setup? Are you even using a WUP-028 or clone thereof? For reference, I am taking about this adaptor:

As far as I can tell, you're trying to connect some not-even-remotely-GameCube controller using not-even-remotely-GameCube-related adaptors. Was your intention using Ultimate 2 Wireless as a GameCube controller on Switch (analogue trigger support)?
