[Bug 449392] Re: gps usb receiver not recognised anymore

[Bernd Zeimetz]

Hi,

thats not a bug in gpsd - udev will assign a new tty number to your device if
the old one is occupied, for example by removing a device in a not-so-nice way.
You could write an udev rule specifically for you device to ensure it is
symlinked to /dev/gps for example, which ensures that your device name doesn't
change. Unfortunately thats nothing I can fix in gpsd. Enabling usb auto
detection might help you, too - it should register the device automatically, not
depending on the name. You don't even need to specify a fixed device in the
configuration for that, only a socket gpsd listens on.

Cheers,

Bernd
