Add support to the Alienware 17 R5 computer

After running akbl --block-testing this is what I get under Arch Linux 4.18.9-arch1-1. After clicking connect, I get the following:

When clicking TEST BLOCK I get an endless stream of:

packet=[  2|  6|  0|  0|  0|  0|  0|  0|  0]	 legend=set_get_status

packet=[  2|  7|  3|  0|  0|  0|  0|  0|  0]	 legend=reset, command=RESET_ALL_LIGHTS_OFF

and I have to kill the process.

Hope you can guide me to get this working. I can do USB capture from Windows if needed.

Hi @seirios , it is always nice of having feedbacks of new computers. Saddly I'm currently kinda busy developing some features for the software. I'll come back when I finish them!

Hello @seirios ,

It makes long time. I still having no real solution for this but have you tried to update the variable DATA_LENGTH to 12? It seems to fix many problems in some computers.
