I want write application that will be connection with external devices via usb/rs232/bt.
I was searching websites and I know now that I need phone with Generic Connection Framework (MIDP 2.0) for rs232 and optional api for bt.
But ... what with USB ?
There is posibility to use them from j2me ?
Theoretical it is stream connection ... like rs232 so maybe its will be work via CommConnetion ?
