Re: [Gpsbabel-misc] Port /dev/ttyUSB0 not initialised on Linux 64 bits

[Guillaume A. <gui...@gm...>]

Hi,

I used the flag, and I found this:

$ gpsbabel -D 4 -t -r -w -i m241 -f /dev/ttyUSB0 -o gpx -F data.gpx
GPSBabel Version: 1.3.6
options: module/option=value: m241/erase="0" (=default)
Opening port /dev/ttyUSB0...
gbser_init("/dev/ttyUSB0")
Failed to open port (Permission denied)
mtk_logger: Can't initialise port "/dev/ttyUSB0"

It seems to be (only) a file permission issue. I didn't know it matters as I
didn't have to run it as root on my other PC (Ubuntu 9.04 / 32bits).
In running gpsbabel with sudo, I can now download successfully the gpx file.
Changing the permission with chmod o+rw makes it always work.

It could help to display by default the "Failed to open port (Permission
denied)" error message to avoid investigating so long for a simple thing.
Thanks a lot for your help.
Guillaume
