LibreSDR - Support for USBtty devices

[BeckGyver]

I would like to connect USB to Serial adapters to the USB-OTG Port of the Zynq-SDR/LibreSDR to add new features. Right now the device is detected but not usabel as TTY.
I am using CH430 and ESP32 devices as client.

One Project in this context:
Switchable Filter on the Input controlled via Serial commands. I have a PCB available and a small programm to control the ESP to switch between 8 filter banks (Lowpass, Highpass and Bandpass).

If you like this Idea I can share the design files and the ESP source.

After plugging you usb , can you send output of

• dmesg
• lsusb

When plugging in a ESP32 with CP210 USB-Serial I get:

analog@analog:~ $ lsusb

and dmesg:

Right now I notice the ESP32S3 has been handled correeclty and I have a ttyACM available 💯

OK, i will add CH341 driver and CP210x to solve your issue with the 2 other boards

I am thinking if there is a good way to connect this with:
