Hi,
please note that this is not a forum and not a user help lines, its a bug tracker. Please fix your device and permissions issues first, with the help from a debian-user mailinglist for example, and if you can send a proper report, do so. > Now I am confused that none of the previously working steps led to any output > on my device port. what is a "device port"? > In the past it wasn't possible to directly read /dev/ttyACM2 because of > permission issues. permission issues are not a problem that gpsd can fix for you. Use udev rules or whatever else is necessary. > The necessary information are posted here: > https://forum.ubuntuusers.de/topic/gpsd-mit-ericsson-f5521gw-mobile-broadband-mod/#post-6727147 > . > For now I can only report that gpsd can't read from the pipe mentioned in > this post.

Thas a LTE modem or something similar, you'll probably have to switch it into gps mode first. Nothing gpsd will do for you. So basically: 1. fix your permission issues (using a pipe is not a fix!), maybe using udev or whatever else is necessary. 2. learn how to put your modem into a working mode 3. trigger gpsd to read from you device. If you then run into bugs, run gpsd in debug mode...
