USB Dongles on Linux

RTDynamics products can be unlocked with a USB Dongle as well as a file based node locked license. On Windows using the USB Dongle is straightforward, attaching the USB Dongle to any USB slot is sufficient, no further setup is necessary. However on Linux, some one-time-setup is necessary, for which we provide shell scripts. Please contact support with the version information of your Linux distribution to get the script.

The USB Dongle support is available on Linux starting with the 4.1.Beta4 release.


If you see error messages on the console related to dongle not being detected, you may check the following and contact support with your findings:

  • Type “lsusb | grep 0e50”, this command shall output the following (device and bus ids may change, that is OK):

    Bus 001 Device 007: ID 0e50:0002

  • Type “ls -alF /dev/bus/usb/001/007”, replace 001 with the Bus id and the 007 with the device id from the output of lsusb. The file must exists and the permissions must be “crw-rw-rw”.
  • Type “ls -alF /etc/udev/scripts/matrix-rule-handler”, the file must exist.
  • Type “ls -alF /etc/udev/rules.d/99-matrix.rules”, the file must exist.
