I have tried a new piece of software (dg100ctl - not in Debian), here are the error message I get before I unload the module (the -p command is used the get the current configuration of the device, hence, read only access I guess...): $ dg100ctl -p open /dev/ttyUSB0 failed: Input/output error dg_100_send: write failed: Bad file descriptor After unloading the module and switching on the device again, it works as exepected: $ dg100ctl -p Logging info : Position, speed, time, and altitude Mem free : 100% WAAS/EGNOS/MSAS : disabled Speed threshold : disabled Distance threshold : 2 m Logging modes: Mode A: by time, every 10.00 seconds Mode B: by time, every 3.00 seconds Mode C: by time, every 1.00 seconds Cheers, Julien -- Julien Valroff <jul...@kirya.net> http://www.kirya.net GPG key: 1024D/9F71D449 17F4 93D8 746F F011 B845 9F91 210B F2AB 9F71 D449 -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
