From a6fbd3b77ad0ad7b3020b4f50659e740ff68c719 Mon Sep 17 00:00:00 2001 From: Jarod Wilson Date: Mon, 18 Jul 2011 16:54:21 -0300 Subject: [PATCH] [media] mceusb: command/response updates from MS docs I was recently pointed to the document titled Windows-Media-Center-RC-IR-Collection-Green-Button-Specification-03-08-2011-V2.pdf which as of this writing, is publicly available from download.microsoft.com. It covers a LOT of the gaps in the mceusb driver, which to this point, was written almost entirely by reverse-engineering. First up, I'm updating the defines for all the MCE commands and responses to match their names in the spec. More to come...
