ttyUSB0 and GPS
in [Debian]

From: Dale on 10 Dec 2009 18:20 Hi All, Does anyone know how to lock a GPS down to use ttyUSB0 all the time, whether it get plugged in and out of the USB port? Basically I want it to reclaim ttyUSB0 after it have been removed from the USB port and then plugged back in. Currently when I unplug the USB GPS and plug it back in it takes the next ttyUSB* inline ie ttyUSB3 for me currently as I have a USB 3G dongle occupying ttyUSB1 and ttyUSB2. I have looked around in udev ie /etc/udev/ and /etc/udev/rules.d/ to find the file where I can lock it to ttyUSB0 but had no success.

I have gpsd all configured, I want to nail this device down in that if it gets unplugged that it always gets ttyUSB0 even when there is other USB devices plugged into that machine.

Thats what I thought you wanted to do /etc/default/gsd # Default settings for gpsd. # Please do not edit this file directly - use `dpkg-reconfigure gpsd' to # change the options. START_DAEMON="false" DAEMON_OPTS="" DEVICES="/dev/ttyUSB0" USBAUTO="true" Works here but of course YMMV Wayne -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

Udev will automatically assign first available "free" device. Keeping gps at higher number will not normally interfere with this. -- Regards, Sudev Barar Read http://blog.sudev.in for topics ranging from here to there.
