>Description:
The ring of LEDs will not stop blinking after the controller is plugged into a USB port. It's very distracting, and detracts from usage.
>How-To-Repeat:
Plug in an Xbox 360 controller.
>Fix:
A reworked patch was applied to uhid.c

Credit where credit is due. The original patch was submitted some seven years ago, and this contribution is simply a rework, as the original seems to have been pruned during revisions and rewrites to uhid.c over the years.
