• Insert module manually, only since the 3.19 kernels and following:

 # modprobe snd_seq_midi

• Check loaded USB Midi module:

 # lsmod | grep usb

• Check your hardware, for presence:

 $ lsusb
 $ amidi -l
 $ aconnect -i or aconnect lio 

• Check your hardware, for actual input:

 aseqdump -p ##

(where you should replace ## with the client number of your keyboard from aconnect -i)

• Create connection in patchage:

 $ a2jmidid -e

(After starting jack)

• is on the Linux-USB list of vendor IDs

http://www.linux-usb.org/usb.ids

as:

05e4  Free shared USB VID/PID pair for MIDI devices

and returns here as it should as:

 ID 16c0:05e4 Van Ooijen Technische Informatica Free shared USB VID/PID pair for MIDI devices

The short manual on the ebay page reads as follows:

Plug and play, no driver or installation needed. Just plug it into a free USB slot and your OS will recognize it. 
Choose USB Midi device in your software settings and you're ready to go.

Two controller mode:
*   Mode 1: Changing whole presets. The controller sends program change messages. 
The LEDs indicates which preset is working.
*   Mode 2: To activate this mode, press buttons 2&3&4. To change back to mode 1, press buttons 1&2&3 
(All LEDs will blink for half a second to indicate this).

 In mode 2 the controller sends control change messages. It allows you turn functions/effects on and off individually. 
 The LEDs indicate their status.                    
 In mode 2, press a button for 10 seconds to switch to momentary mode. (All LEDs will blink for half a second to indicate this).
 It allows you to use non-on/off functions like 'previous/next preset', 'tape deck play' etc.
 The LEDs do not light up in momentary mode since it's unnecessary.

External pedal input. You can connect any standard pedal with a 6.3mm (¼ inch) stereo jack.  Using an “insert” or “Y-shaped” cable.

To use the full range of the pedal you may have to calibrate it.
Calibration:  Step 1:turn the pedal to minimum position and press button 1 AND button 3. 
              (All LEDs will blink for half a second to indicate this).
              Step 2:turn the pedal to maximum position and press button 1 AND button 4. 
              (All LEDs will blink for half a second to indicate this)
              The device will save the calibration data so you only have to do it once.

The Full Monty: HugarianPedal + IDJC + D::Light

0. Set your pedal's keys to Note/Momentary as described above.

1. Create connection in patchage:

 $ a2jmidid -e

(After starting jack, by, i.e., starting idjc already. It doesn't matter, you'll just restart it later. This is needed to provide midi input to IDJC)

2. Start qmidiroute

3. Go back to Patchage, after successful launch of the a2jmidid -e daemon and re-launch of IDJC,

4. Go back t qmidiroute, hit Ctrl-G to re-arrange the view, and now connect the following:

From the the a2j Output box (Left one): The RED output labelled: "USB Midi ontroller [XX] (capture): USB Midi Controller MIDI 1"

Goes to BOTH:
in the idjc input box (right one)
* RED midi_control 
in the a2j input box (right one)
* RED qmidiroute [XXX](playback): in
 and either create the inputs/outputs pairs needed like this, or load them if you already did it:

(This is to "speak" a language D::Light understand, since it doesn't do Go on CC, and receive all 4 PC from the pedal as the same event)

Hit the "Add New MIDI Route" button to create a new tab;

Set input to         "controller"
Set Channel to        1 / 16
Set Controller to     0 / 96    (that is the value of the first button)
Leave value to        0 / 127  

Set output to        "Note" 
Set Channel Offset to 0
Set Note Offset to    0
Set Velocity at       0 / 127
Leave ALSA port to 1 

Hit "Duplicate" and do the same with Controller to "97"

Save your map!

In D::Light / Setup, refresh the Midi section with the blue arrows and select "Out1" In D::Light / Midi, you should see the output when you hit button 3 or 4 of the pedal; assign them as you wish.
