      @aha_1980 Thank you so much for your ideas. Both problems solved. After reconfiguring aptitude stuff to use "stable" instead of hard-coded "jessie" and half-a-day-long upgrades and cleaning the mess I really got not only higher version of Qt, but as well QParallelPort working as planned. Definitely worth the effort (even if I did not expect the upgrade to take so much time.) My mistake. I missed this single character overload to append(). Thank you for pointing me there. Now I got completely rid of that development/release conditionals. Case closed, thanks to all who assisted.

      yes it should. you can read about it here http://manpages.ubuntu.com/manpages/utopic/man1/pumount.1.html it seems to expect the device to be mounted under /media.

      @SGaist I'm not sure, but I believe solid needs udev. I'm using busybox with mdev. However, I found a solution with find and grep. If I know I have to find where, for instance, sda is connected on my 4 ports: find /sys/bus/usb/devices/usb*/ -name dev -path "*usb1*sd*" | grep -E sda find /sys/bus/usb/devices/usb*/ -name dev -path "*usb2-1.1*sd*" | grep -E sda find /sys/bus/usb/devices/usb*/ -name dev -path "*usb2-1.2*sd*" | grep -E sda find /sys/bus/usb/devices/usb*/ -name dev -path "*usb2-1.4*sd*" | grep -E sda The return value is 1 if there is no entry matching and 0 if there is. I wrapped this in a function with sd_ as variable and it works as supposed. Cheers, McL

      Exact, QSerialPort doesn't call the USB stack directly. Typically for FTDI devices, you would install the FTDI Virtual Com Port driver and then you have a "classic" com port. AFAIK the ARDUINO uses RS232 so it should act also like a serial device.
