This applies to Ubuntu and Ubuntu-based Linux versions and all MXWendler versions
Problem
You start with a USB dongle attached but the log states there is no dongle found.
Background
Actually a dongle is found, but it cannot be read because of a udev permission issue. The dongle can be read, but no commands like 'Give me the dongle serial' can be sent to the dongles.
Solution
For a first test, you can start MXWendler as root. If the dongle is found, then it is a permission issue. Enable the correct permissions for all users the USB dongle. Enable full access to the dongles with the following command sequence issued in a terminal:
$ sudo touch /etc/udev/rules.d/999-ft-mxw.rules
$ sudo vim /etc/udev/rules.d/999-ft-mxw.rules
Enter this line:
SUBSYSTEM=="usb",ATTRS{idVendor}=="096e",MODE="0666"
Then restart udev service
$ sudo /etc/init.d/udev restart
and re-plug the dongle.
