refers...

The issue is this- the gamepad detection and install scripts use the existence of /dev/js0 as the trigger for adding this device. Unfortunately /dev/js0 is also added for at least one other device (internal notebook accelerometer as per above post).

I would like to modify the detection and install scripts to use another method to find the gamepad. I'm thinking the output of lsusb for example... but I don't have a gamepad to test. If anyone has one, please can they assist with testing and post the output of
Code: [Select]
lsusb -v
(obviously this will be executed after sshing into the media director to which the gamepad is connected) for me.

Ta.

PS, if anyone else with actual skills wants to take this over, feel free ;-)

I would probably talk to udev to get usb joystick devices.

What's wrong with a notebooks accelerometer to be used as a game pad?

My daughter asked the same question.

Alright,

*after much reading*

Someone that has a USB gamepad that they would like to continue using in the next release of the next snapshot of the next update of the wonderful and all-powerful LinuxMCE 10.04, please post their output from
Code: [Select]
udevadm info --query property --name /dev/input/js0

Thanks. I may be getting somewhere on the AVWizard_Gamepad_Detect part but now for the polling script... Gamepad_Detect....

Thom, would you mind posting the output of
Code: [Select]
udevadm info --attribute-walk --name /dev/input/js0
from your joystick machine?

Ta

Edit: Almost forgot- please also check that the following script returns what you expect from your two machines-

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Thom... I need some help here, buddy. The breadcrumb trail has got me this far only.

Here's the install and detect system as I understand it:

At Boot Time:
==========
AVWizard_Run.sh (which runs every boot if I recall):
calls: AVWizard_Gamepad_Detect.sh, which, in turn:
  1. installs lmce-usb-gamepad (if it thinks it's needed)
  2. returns "/usr/pluto/bin/USB_Game_Pad -l /var/log/pluto/avremote.log -r dcerouter -d -1003 -H localhost -P " or something to that effect.
AVWizard_Run.sh then sets the returned value in 2) to the environment variable GamepadCmd.

OK, so the package is installed if required, but I can't see why the GamepadCmd variable is set because I can't figure out where/if it's ever used?

Every 5 seconds:
=============
Gamepad_Detect.sh
  1. If gamepad not already running but it is detected, send appropriate message to dcerouter.

----------------------------------
So what I'm thinking is that instead of polling every 5 seconds, we just setup a rule in the udev system that detects the gamepad either on boot or on plug in and fires off a script that does the whole shebang- installs the package (if not installed) and sends the message to the router.

The only snag is... that "GamepadCmd" bit... what is that used for and where does it come in. Is it a necessary step I'm missing out?

...
 snag is... that "GamepadCmd" bit... what is that used for and where does it come in. Is it a necessary step I'm missing out?

The GamepadCmd environment variable is read by the actual AVWizard (a C++ program) and it's contents are executed by AVWizard to start the GamePad device.  It also takes care of removing the device when the AVWizard completes.

When AVWizard completes, the GamePad Radar (Gamead_Detect.sh) takes over detection..

It seems to me that the easiest way to implement this might be to simply alter the existing detection scripts.  Run 'udevadm info --query property --name /dev/input/js0' on each detected device and grep it for 'ID_INPUT_JOYSTICK=1', if that returns a value then activate the gamepad.  Likewise don't activate the device in the radar (or set GamepadCmd) if the grep returns nothing.  The udev rule would likely be more efficient on cpu resources.

To illustrate my previous e-mail, and as tschak pointed out earlier, devices will either have or not have ID_INPUT_JOYSTICK=1. 

Here is the udev output from the mouse in my VirtualBox Virtual Machine that is consistently detected as a joystick, notice there is no ID_INPUT_JOYSTICK=1, it has ID_INPUT_MOUSE=1 instead.  Why it is mapped to /dev/input/js0 as well as the normal mouse input I have no idea.

Code: [Select]
# udevadm info --query property --name /dev/input/js0

Working on it.  :)  Here's a Gamepad_Detect.sh and AVWizard_Gamepad_Detect.sh that are no longer detecting my mouse as a game pad.  I'll submit to svn if I can get confirmation that it works for someone else with a gamepad and for someone who has always had the issue of improper detection of non joystick devices.

Alright, after conversation with tschak on irc I understand the issue a little bit more and it will require a bit more refactoring of the detection scripts and of the USB_Game_Pad device to function the way it needs too.  I'm am first fixing the detection scripts to detect ANY joystick existing on /dev/input/js?.  Then (hopefully) figure out USB_Game_Pad so that it will ignore non-joystick devices that present at /dev/input/js?.
