Error on M18x R2

[vagkaefer]

First thanks for the repository, in a few days I will see if I can contribute to it.

I saw the https://github.com/bchretien/AlienFxLite/issues/2 issue. But I do not get the solution.

The error is the same: " The application was unable to communicate with the alienfx device. The device is not present, or the application lacks sufficient rights to access the device."

I ran the commands as root: $ sudo java -jar AlienFX.jar $ sudo alienfx-lite None worked ;/ The return is Device found: 187c:0518

The sudo lsusb | grep -i alien' return: Bus 004 Device 005: ID 187c:0518 Alienware Corporation

I'm ussing Arch Linux (4.7.4-1-ARCH x86_64).

How to fix this problem? Tks

Just a quick check... Try to run alien-fx as root. If it works, you may have to make the user able to use that usb device

[bchretien]

The M18x R2 is not supported (yet), however the error message should clearly be clarified in that case. I'll add that controller, but you'll be my beta tester ;)

@Soulsuke I ran everything as root. Does not work!

@bchretien I'll be your beta tester. With pleasure ;D

Here is more information about the device. I hope it helps.
