Conflict between joypad and camera

Hello to all;
I am just now starting to cram into my old brain the concepts of HAL components...Presently, on a different computer with Axis running a router table, I have it set up to run the identical joypad used in the wiki for joypad setup...I merely copied the code and followed all directions and the joypad functioned as intended...That did not provide me with the knowledge necessary to really do anything with HAL...I have recently followed instructions for installing a camera on the same Axis install (thanks to psha's help) and it also functions properly as far as I can tell...

The problem I found was that in order to get the video camera to work, I had to disable all lines of code in the various file locations (.ini, *.hal) which made reference to the operation of the joypad...So, I can either enable the joypad, or the video camera, but not both at same time...I am 99% sure this involves a conflict between the two devices controlled in and through HAL components...I am not sufficiently knowledgeable enough presently to actually identify what that presumed conflict is, nor provide a resolution to that conflict...I do believe that this is a HAL conflict and thus I am studying diligently to learn to be self-sufficient with HAL, but I realize it will be a lengthy learning curve and I would like to have a more immediate solution...

Any suggestions will be happily accepted...I will provide any error reports or other information as requested.

Thank you in advance.

John,
Thank you for your very quick response...

I will gather file/error information and post it...in the mean time I will try your suggestions, un-commenting individual lines to see where it breaks...

I have already read your suggested HAL information, as well as all others I could find...I know I am not competent at present, but I will be if I live long enough...lol

Thank you for your input...I will keep you posted...

are both usb devices specificly enabled in your permissions list in ubuntu

Using the suggested method of isolating the line of code that breaks, I received the following error, in the third line of custom_postgui.hal relating to the joypad:

insmod: error inserting ' /usr/realtime-2.6.32-122-rtai/modules/emc2/sum.ko': -1 File exists
custom_postgui.hal:11 exit value: 1
custom_postgui.hal:11 insmod failed, returned -1

The line that broke it is as follows:

"loadrt sum2 count=2"

cncbasher: I don't know how to check if they are both enabled, and don't know exactly where to look to see if they are and with permissions....btw, thank you for your input

John,
Yes, I do have another file which has the same lines as follows:

"loadrt sum2 count=3" this line is located in my "router.hal" file....

I increased the number in the custom_postgui.hal file to 5, and when starting axis, received the same identical error:

Mike

John,
I next tried increasing the count= number to 5 in the "router.ini" file and reverting the custom= to its original 2 in the "custom_postgui.hal" file yielding the same identical error as before....

Mike

John,
Next, I increased to 5 the count= numbers in both of the files afore-mentioned, still with identical error...
