Game Input MultipleXer

Hi, everyone,
I am a newbie to using GIMX(serialusb). Currently, I use the serialusb source and build it on the Pi4, but when I run the serialusb-capture.sh , I always got a timeout error.

```
Failed to start the proxy: initialization timeout expired!
```
This is my device flow:
USB keyboard-> pi4-> usb to uart(CP2102, FT232)-> arduino leonardo -> window10 pc.
I also use other arduino board to test the usb to uart cable, I can receive the data from the cable.
my arduino board have use GIMX launcher to update the firmware.

Does anyone know what's the timeout issue?

thanks a lot.

Did you ever find a fix, This is my setup too.

It's not fixed yet, but I'm trying to buy a CP2104 chip for testing. I am not sure which part is wrong.

Update:
When using CP2104 with the pro micro board, the GIMX is working now.

Thanks for the report.
