Hello all, hoping some awesome people here in the XBMC forum can help me. I have a remote wonder plus x10 rf remote that I would like to get working in xbmc linux (any flavor really, openelec preferably).
The problem is that a patch is needed and I HAVE THE PATCH but don't know how to adapt the patch for kernel 3.14.11. It was written for kernel 2.6.20
All I need is someone to help adapt this patch to 3.14.11 but please show me how you did it? I would like to learn from this.
Here is the drive patch for 2.6.20:
Here is the jist of the problem and all the technical details.
Now I am not a linux guru and have never patched a kernel but could this work in XBMCbuntu or openelec?
THANK for reading..

/*
* USB ATI Remote support
*
* Copyright (c) 2011, 2012 Anssi Hannula <[email protected]>
* Version 2.2.0 Copyright (c) 2004 Torrey Hoffman <[email protected]>
* Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev
*
* This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including
* porting to the 2.6 kernel interfaces, along with other modification
* to better match the style of the existing usb/input drivers. However, the
* protocol and hardware handling is essentially unchanged from 2.1.1.
*
* The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by
* Vojtech Pavlik.
*
* Changes:
*
* Feb 2004: Torrey Hoffman <[email protected]>
* Version 2.2.0
* Jun 2004: Torrey Hoffman <[email protected]>
* Version 2.2.1
* Added key repeat support contributed by:
* Vincent Vanackere <[email protected]>
* Added support for the "Lola" remote contributed by:
* Seth Cohn <[email protected]>

*
* Hardware & software notes
*
* These remote controls are distributed by ATI as part of their
* "All-In-Wonder" video card packages. The receiver self-identifies as a
* "USB Receiver" with manufacturer "X10 Wireless Technology Inc".
*
* The "Lola" remote is available from X10. See:
* http://www.x10.com/products/lola_sg1.htm
* The Lola is similar to the ATI remote but has no mouse support, and slightly
* different keys.
*
* It is possible to use multiple receivers and remotes on multiple computers
* simultaneously by configuring them to use specific channels.
*
* The RF protocol used by the remote supports 16 distinct channels, 1 to 16.
* Actually, it may even support more, at least in some revisions of the
* hardware.
*
* Each remote can be configured to transmit on one channel as follows:
* - Press and hold the "hand icon" button.
* - When the red LED starts to blink, let go of the "hand icon" button.
* - When it stops blinking, input the channel code as two digits, from 01
* to 16, and press the hand icon again.
*
* The timing can be a little tricky. Try loading the module with debug=1
* to have the kernel print out messages about the remote control number
* and mask. Note: debugging prints remote numbers as zero-based hexadecimal.
*
* The driver has a "channel_mask" parameter. This bitmask specifies which
* channels will be ignored by the module. To mask out channels, just add
* all the 2^channel_number values together.
*
* For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote
* ignore signals coming from remote controls transmitting on channel 4, but
* accept all other channels.
*
* Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be
* ignored.
*
* The default is 0 (respond to all channels). Bit 0 and bits 17-32 of this
* parameter are unused.
*

============================== CUT HERE ==============================
We log USB data for the RF receiver in window 2.
In window 1 we enable USB monitoring and unload and reload the ati_remote
module.
We can see the 2 initialization strings being sent to the RF receiver via the
interrupt out (Io) lines
and then when we press the Firefly key on the FF remote we see the repeated USB
packets sent by the RF remote (14658010).
However when we press any keys on the ATI remote no data is logged by usbmon.
This indicates that the RF receiver is ignoring data sent by the ATI remote
when initialized by the ati_remote modules.
However when we load the modified version of the ati_remote module we see:

Here we can see the modified initialization sequence being sent to the RF
remote and when we press the Firefly key on the FF remote we see the repeated
USB packets sent by the FF remote (14658010)
and when we press the ATI key on the ATI remote we see the repeated USB packets
sent by the ATI remote (15222d20).
The conclusion is that the RF receiver initialization must be changed in the
ati_remote module in order to support the ATI remote.
So what needs to happen is the ati_remote module needs to be updated. Now I have found how to recompile the kernel 2.6 module but I would like to find a way to do this for the latest kernel.
Please see the link below. I am not a linux guru and do not know how to get this to work for a more recent kernel. So I am hoping someone here maybe able to help with this. There are quite a few people out there with the remote wonder plus who would like to use it outside of windows. I currently have a windows xbmc install just to use this remote. Help me get off windows and use my remote with linux.
Here is the link to a thread where a guy got his remote wonder plus to work in linux. I am not able to do what he did and also have a newer version of linux, However I may consider getting an older version if that's the only way to do this.

If like me you have an ATI Remote Wonder in his "plus" version, you could not make it work properly with the "ati_remote" basic module.
So I'll explain in this tutorial how settled and set!
(I realize this tutorial Ubuntu 12.04.4-3.11.0-18-generic)
Started by connecting the receiver and then ATI typing this command:
Code:
lsusb
That should be displayed
Code:
0bc7: 0004 X10 Wireless Technology, Inc. X10 Receiver
The receiver and therefore well detected by Linux!
1 Module Creation and autoloading
We'll have to compile a new module containing the bases "ati_remote" but integrating our new remote.
To begin creating a folder "atiplus" or you want:
Code:
sudo mkdir atiplus
Returned to the folder with:
Code:
cd / atiplus
Then creates a new file in which you copied the source code of the new module:
Code:
sudo gedit ati_remote_plus.c
Link the source code for the new modules: pastebin.com/eP1wiGtT
(The source code for the new module from this source: www.spinics.net/lists/linux-input/msg28006.html )
I purposely changed the new source code to disable the "mouse" on the remote control that generated "freeze" at rehearsals!
Then you need to create a final "Makefile" file:
Code:
sudo gedit Makefile
We copy in there:
Code:
obj-m: = ati_remote_plus.o
KDIR: = / lib / modules / $ (shell uname r) / build
PWD: = $ (shell pwd)
all:
$ (MAKE) $ C (KDIR) M = $ (PWD) modules
clean:
$ (MAKE) $ C (KDIR) M = $ (PWD) clean
Is saved and you type:
Code:
make
Now that the module and compiled, we will have the loaded at startup.
We start by creating a folder to receive the module:
Code:
sudo mkdir p / lib / modules / $ (uname r) / kernel / drivers / ati_remote_plus
The module is copied to the folder:
Code:
ati_remote_plus.ko cp / lib / modules / $ (uname r) / kernel / drivers / ati_remote_plus /
Then we will edit the "modules" file that launches the modules ... niark niark :
Code:
sudo gedit / etc / modules
Then you add in the wake of the modules:
Code:
ati_remote_plus
We update the list of modules:
Code:
sudo depmod
Last steps to prevent the loading of the module ati_remote "basic".
We'll have to add the module to the blacklist, so you edit this file:
Code:
sudo gedit /etc/modprobe.d/blacklist.conf
Add all at the top of the list:
Code:
# Replaced by ati_remote_plus
ati_remote blacklist
From there you can restart the computer, start the "ati_remote" module will not be loaded and the module "ati_remote_plus" we have compiled shortly before the replacement.
2-detection and configuration of the remote
We'll installed ir-keytable to test and set our remote:
Code:
sudo apt-get install ir-keytable
Once finished installing type:
Code:
ir-keytable
You should see a few details this:
Code:
Found / sys / class / rc / rc0 / (/ dev / input / event3) with:
Driver ati_remote, table rc-ati-x10
Supported protocols: other
Enabled protocols:
Extra capabilities: <access denied>
ir-keytable does detect our remote!
To test the remote control type:
Code:
keytable ir-t d / dev / input / event3
[Color = red
Warning replace your well !! input [/ color]
Press the buttons you should see entries appear this way:
Code:
1396193942.353173: event key down: KEY_3 (0x0004)
1396193942.353173: event sync
1396193942.353186: event key up: KEY_3 (0x0004)
1396193942.353186: event sync
We will now configure the buttons.
To do this we will create two configuration files:
Code:
sudo gedit / lib / udev / rc_keymaps / ati_x10
Copy / paste:
Code:
# Table ati_x10 type: OTHER
0x000A KEY_MUTE
0x0025 KEY_PLAY
0x0029 KEY_PAUSE
0x0028 KEY_STOP
0x001d KEY_LEFT
0x001F KEY_RIGHT
0x001a KEY_UP
0x0022 KEY_DOWN
0x001E KEY_KPENTER
0x0021 KEY_BACK
0x001b KEY_I
Code:
sudo gedit / etc / rc_keymaps / ati_x10
You copy into it the same as in the previous file!
These are but settings but you can safely change the assignments as you like!
Finally we will ensure that our config file is automatically loaded:
Code:
sudo gedit /etc/rc_maps.cfg
Copy it in the front line:
Code:
* Rc-ati-x10 / lib / udev / rc_keymaps / ati_x10
Just above:
Code:
* Rc-twinhan1027 / lib / udev / rc_keymaps / twinhan_vp1027_dvbs
Voila! it's over! Direction the couch to enjoy :)THANK for reading..
