This app supports USB to serial converters based on
- FTDI FT232, FT2232, ...
- Prolific PL2303
- Silabs CP2102, CP2105, ...
- Qinheng CH340, CH341
and devices implementing the USB CDC protocol like

- BBC micro:bit using ARM mbed DAPLink firmware
To connect USB to serial converters, your android device must support USB OTG aka. USB host mode. Most devices support this today, but in case of issues check with one of the various USB test apps, if host mode is enabled in your android kernel.
