Garmin GPS no longer makes /dev/tty entry

[BigBananaMan]

Well I seem to be having the same exact problem as the original post. I try to run gpsd and...

bananaman@curious-george:~$ sudo gpsd -N -D 6 usb:
gpsd: launching (Version 2.37)
gpsd: listening on port gpsd
gpsd: shmat(0,0,0) succeeded
gpsd: shmat(0,0,0) succeeded
gpsd: shmat(0,0,0) succeeded
gpsd: shmat(0,0,0) succeeded
gpsd: successfully connected to the DBUS system bus
gpsd: running with effective group ID 0
gpsd: running with effective user ID 0
gpsd: opening GPS data source at 'usb:'
gpsd: device open failed: No such file or directory - retrying read-only
gpsd: read-only device open failed: No such file or directory
gpsd: GPS device usb: nonexistent or can't be read

As you can see I tried using "usb:" but it also failed like "/dev/ttyUSB0" did. dmesg and lsusb match what SSamiK had except that mine never worked from the start. My GPS is a Garmin GPSmap 60CSx. The GPS is set to NMEA in/out at 4800 baud and displaying that it is "connected". After trying what SSamiK said in his last post I got...

bananaman@curious-george:~$ sudo gpsd -N -D 6 /dev/ttyUSB0

and when I ran xgps in a second window to test it, the following was added in the first terminal:

gpsd: client 127.0.0.1 (0) connect on fd 6
gpsd: checking client(0)
gpsd: <= client(0): w+x
gpsd: client(0): assigning channel...
gpsd: User r8-)8-)8-)equires 2, channel type is -1

gpsd: client(0): channel 5 already active.
gpsd: => client(0): GPSD,W=1,X=1231204502.736271

It could not open "devices" under /proc/bus/usb because it was not there so I tried to mount it with...

sudo mount -t usbfs usbfs /proc/bus/usb

and running gpsd again. This time it returned nothing when I ran gpsd with -N -D 6. When I try running Gpsdrive it says I have no GPS and xgps just freezes when I try to run it. This seems to be a long series of problems and not just one. I've probably fixed it 4 or 5 times from solutions and tutorials in threads spanning across several forums only to find another problem waiting in line.

kitplummer, have you tried to comment out the blacklist and have you had similar results to mine? Anyone else?
I've been working on this for two days straight and I think my eyes are bleeding now so I'm going to take a really long sleep.

I haven't made any breakthroughs but I have discovered something kind of obvious. gpsd works on port 2947 so what happens if you telnet to that? Well you can telnet to it and if you look in the man page for gpsd you can see all the commands it uses which can be entered through telnet.

bananaman@curious-george:~$ telnet localhost 2947
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
a
GPSD,A=?
b
GPSD,B=9600 8 N 1
x
GPSD,X=1231447275.914733
y
GPSD,Y=?
z
GPSD,Z=1
f
GPSD,F=/dev/ttyUSB0

I punched in a few letters and it appears that the GPS really is connected to gpsd and the problem lies somewhere between gpsd and the applications. Well that's one step closer at least, any ideas where to take this next? So far I've had no luck with qlandkarte, Gpsdrive, xgps, and kismet.

Hi there, I would like to buy a outdoor device like garmin extrex H, vista HCX ord legend hcx.

For geocaching, realtime mapping and wardriving

Befor buying I want to know if one of these devices work properly with gpsd (ubuntu 8.10 64bit) .

I found a small tutorial...

1. edit /etc/modprobe.d/blacklist and add the lines

# stop garmin_gps serial from loading for USB garmin devices

# blacklist garmin_gps

To allow the USB devices to be read and written by a non-privileged user, create a named /etc/udev/rules.d/51-garmin.rules with the following contents:

SYSFS{idVendor}=="091e", SYSFS{idProduct}=="0003", MODE="666" 

source: http://www.gpsbabel.org/os/Linux_Hotplug.html

2. When the file /proc/bus/usb/devices is NOT present, it may be because the usbfs is not mounted. One way is to try mounting it, (which may fail if there is no directory /proc/bus/usb) Code:

sudo mount -t usbfs usbfs /proc/bus/usb 

Source: http://ubuntuforums.org/showthread.php?t=670878

start  "gpsd -nND2 /dev/ttyUSB0"


3. add  

none /proc/bus/usb usbfs deflautls 0 0

to /etc/fstab

I am not sure if this works...please let me know.


And whats the output of

cat /dev/ttyUSB0

?


Cheers

Hey JohnnySteel, I checked out your guide. I recently had to reinstall the OS because of hardware failure and after performing every step in your guide I realized I essentially just did everything I did before. I also got the same results. Everything worked out fine until I tested it.

bananaman@curious-george-2:~$ cat /dev/ttyUSB0
cat: /dev/ttyUSB0: No such file or directory

I then telneted into localhost on port 2947 and got the same result as before.
I'll keep searching and messing around with it when I get the time but I'm stumped for now. Although the Garmin GPSmap60CSx is a great little GPS and one of my best upgrades ever. (previously I used outdated, water damaged maps and a lensatic compass. I kid you not.) Until proven otherwise I have to say it's not Linux compatible. Other people have had luck with other Garmins so you might want to ask some of the people that have had success. Click here for a list of GPSs that the gpsd makers have tested. I suggest you get one that can store data on a micro SD card otherwise you won't be installing any state or large custom maps.

I couldn't get Viking or Qlandkarte to recognize my Garmin GPS on Ubuntu 9.10 until I ran the programs with sudo, and both then worked. It appears to be a permissions issue on the device files and I'm still looking for a nice fix to get around having to run this stuff as superuser.

Update: Aha! I editted my user id's properties and gave it all privileges, logged out, logged back in and Viking was able to download from my GPSmap60 without sudo. I'm not sure which privilege did the trick as there was nothing specific for USB.
