Read and writer data via USB port on Android 3.1

Question

I am trying to write an android app to read and write data from android tablet to our embedded device. The tablet and embedded device are connected via usb to serial converter.

Answer 1

I suggest using the ported usb-for-android lib, which has the PL2303 driver already implemented: https://code.google.com/r/felixhaedicke-usb-serial-for-android

I've used it successfully.
