Game Input MultipleXer

Hello. I am new to the whole GIMX adapter stuff, have heard it CAN used with reWASD as a virtual controller from the computer to a video game console (Nintendo Switch for example), and have heard that you can make a DIY one with an Arduino Leonardo board (as long as it has the atmega32u4 microcontroller), but I am a little curious about one thing: "Is it possible to make multiple GIMX adapters using a single Arduino Leonardo board and dupont Y splitters (single male and dual female on the other), and multiple CP2102 USB boards?"

Let's say for example: "I want to have 7 virtual Switch Pro Controllers, 3 virtual single Joy Con Controllers (Left, right, it doesn't matter), or 7 single virtual Nintendo GameCube Controllers to interact with my Nintendo Switch OLED console for testing with Moonlight Stream. And according to this listing's description on Etsy: https://www.etsy.com/listing/1333156495 ... -wire-male you can use these to actually share the same pins IF you have other stuff to use for it. So is it actually possible to do something like this, or no?"

Well it turns out I was right about the Dupont Splitter stuff and the UART adapters working as separate ones. Yes, I know I didn't get the CP2102 UART adapters, but I will do a test to see what happens if needed.

Okay, I've tested the adapters I got and they seem to work for my Arduino Leonardo as GIMX Adapters, but only one can work at the same time. When I try and test two of them connected to the UART adapters, they both disconnect and reconnect and loop back and forth. Is this a bug, or can only one GIMX adapter work on the serial ports of the UART adapters? Unless there is an option to add more serial pin ports (RX/TX) then I could try that.
