X360Key : Fix Micro USB socket false contact

It is possible that some users find difficulties to keep connected the Micro USB in the Xkey remote, making it difficult handling.
This inconvenience is that the plug of the Micro USB cable (supplied with the X360Key module) turns out to be sometimes a fair bit depth to allow the "clipping" of the cable to the remote.
Thus, we offer in picture a simple way to overcome this problem by cutting 1 mm from plastic edge of the Micro USB cable.

With this trick, no more reliability problems. ;)

NB: A cutter is needed for a clean cut of the cable.
