    Hi! I'd like to know some details about how you are running please.

    You say re-running causes segfault, any reason why you need to re-run the server?

    Can you please tell me about your environment? Kernel Version, Distro, etc?

    Does the software otherwise work?

    How many Kuhler-1250s do you have in the system?

    Thanks for filing the bug report. I'll investigate when I get some more information.

    Thanks!

      You say re-running causes segfault, any reason why you need to re-run the
      server?

      Testing, there is no /etc/init.d script so I starting from terminal

      $ ./kuhler_1250

      etc?

        Thanks for providing the information. Can you also do a "lsusb"?

        There is no real detection code for the kuhler right now, so if you have other USB devices with the same VID:PID it could cause this issue.

        The next version will have an attempt at kuhler detection, either with a standalone setup program, or better detection code in the server.

        Thanks!

            AlphaGeek - 2016-11-06

            Thanks for the info. I agree that "Bus 007 Device 004: ID 067b:2303
            Prolific Technology, Inc. PL2303 Serial" is the Kuhler 1250. If Steve
            hasn't already emailed you, you probably don't have permissions as a normal
            user on the /dev entry in your configuration file.

            Two options:

            1. use sudo to start the daemon

            2. (perferred) add yourself to the "dialout" group for the /dev entry, and
              run the daemon/server as a normal user.

            Let us know if that works or if you need some help!

              Thanks for the info. I agree that "Bus 007 Device 004: ID 067b:2303
              Prolific Technology, Inc. PL2303 Serial" is the Kuhler 1250. If Steve
              hasn't already emailed you, you probably don't have permissions as a normal
              user on the /dev entry in your configuration file.

              Two options:

              1.

              use sudo to start the daemon
              2.

              (perferred) add yourself to the "dialout" group for the /dev entry, and
              run the daemon/server as a normal user.

              Let us know if that works or if you need some help!

              Thanks for providing the information. Can you also do a "lsusb"?

              There is no real detection code for the kuhler right now, so if you have
              other USB devices with the same VID:PID it could cause this issue.

              The next version will have an attempt at kuhler detection, either with a
              standalone setup program, or better detection code in the server.
              Thanks!
