-On Linux, you need to give your user access to the USB device.
-
-You can do that by creating a file under ``/etc/udev/rules.d/`` named
-``99-lda.rules`` with the following content::
-
-    SUBSYSTEM=="usb", ATTR{idVendor}=="041f", MODE="0666"
-
-Then you need to tell udev to reload its rules::
-
-    $ sudo invoke-rc.d udev reload
-
-You must also unplug/replug your device if it was already plugged in.
-
-Then, to run the Lab Brick Digital Attenuator (LDA) controller::
-
-    $ aqctl_lda -d SN:xxxxx
-
-The serial number must contain exactly 5 digits, prepend it with the necessary number of 0s.
-Also, the ``SN:`` prefix is mandatory.
-
-You can choose the LDA model with the ``-P`` parameter. The default is LDA-102.
