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 the dongle serial' can be sent to the dongles.

Solution

For a first test, you can start MXWendler as root. If the dongle is correctly used, 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.

Remark The dongle values are never changed, this is only possible for the dongle issuer.
