Hi, I’ve got a really strange problem with my gps on openSUSE 11.0. It used to work in previous versions. My Garmin etrex legend is connected to my notebook via Prolific 2303 USB-serial adapter and runs in NMEA mode. When I connect the device to my computer the output of cat makes sense:

cat /dev/ttyUSB0
$GPRMC,125552,V,5232.4583,N,01325.4415,E,10.8,0.0,120508,2.0,E,S*22
$GPRMB,V,,,,,,,,,,,,A,S*0E
$GPGGA,125552,5232.4583,N,01325.4415,E,8,11,2.0,-5.6,M,43.0,M,,*69
$GPGSA,A,3,02,04,07,08,10,13,16,23,24,25,27,,3.6,2.0,3.0*3E
$GPGSV,3,1,11,02,37,255,45,04,26,216,43,07,70,138,50,08,40,197,46*72
$GPGLL,5232.4583,N,01325.4415,E,125552,V,S*4B
$GPBOD,,T,,M,,*47

Then, being root, I run “gpsd -n -N -D5 /dev/ttyUSB0” to start the deamon and I see some output that seems ok as well. As in older suse versions I expected “telnet localhost 2947” followed by pressing “R” to show me the output of gpsd. But nothing happens. Xgps and gpsdrive are completely unable to connect to the gps receiver, nor can they find it at all. After gpsd is closed cat on the gps gives this output:

cat /dev/ttyUSB0
���xx��xx�xxxx����x�x�����x�xxxx������������x���������x��xx�x�������x���x����x�x��xxxxx���x�x��x�xx�����x����x����x�xxxx��x�x����x��x�x���xx��xx�xxx�xxxxxxxxxxxxxxxxx��

When I ran into that problem I thought about permission issues. I openSUSE 10.3 belonges to the group root, in 11.0 to uucp. So I added myself to the group uucp, where gpsd belongs to. Didn’t help. Seems I must be root.

gpsd -n -N -D5 /dev/ttyUSB0
gpsd: launching (Version 2.37)
gpsd: listening on port gpsd
gpsd: Unable to start ntpshm.  gpsd must run as root.
gpsd: successfully connected to the DBUS system bus
gpsd: running with effective group ID 100
gpsd: running with effective user ID 1000

Strange enough I can read and write to the gps as a user when I use gpsbabel. Anyone has an idea? I appreciate any help. Thanks a lot…

ok, once again… on plugin of the usb-serial adapter with the gps connected and running in NMEA, gpsd is launched automatically.


Jul  4 20:34:57 schlick kernel: usb 3-2: new full speed USB device using uhci_hcd and address 4
Jul  4 20:34:58 schlick kernel: usb 3-2: configuration #1 chosen from 1 choice

Jul  4 20:34:58 schlick gpsd: Action 'add' Launch GPSD to /dev/ttyUSB0 with -F /var/run/gpsd.socket

then cat shows the same strange output as above. telnet can connect to port 2947 but shows no output and gpsdrive does not recognize the gps device.:confused:

I’m keeping an eye on this thread as I have had an issue getting my
Garmin GPSMaps 60CSx working. Wish I could help you though.

Ok, just asked a friend for advice. He is running gpsd 2.32 on gentoo and everything works fine. Anyway, he was willing to update to 2.37 but skipped because of this message:

This version of gpsd has broken the support for the TNT compass and Garmin so they are disabled. If you need it, stay with the previous version for now.

Don’t know if I`ll wait for a new version or install an older one.
Thanks.
