Hi,
I am running LinuxCNC on a Rasperry PI + PiCNC.
The system is built up using the instructions from Kinsa Manka (code.google.com/p/picnc/wiki/CreateRaspbianLinuxCNC).
Until now I am quite happy with this configuration.
Kernel is:
I want to add a USB pendant, but the system does not recognize it properly.
The gamepad is cheap china model (CSL 19638).
Using lsusb, the device gets shown:
But the device is not visible in /dev/input:
The file proc/bus/input/devices is empty
Output of dmesg:
My Ubuntu PC detects the gamepad directy without any problems and generates a file under /dev/input/js0.
Does anybody know why the raspberry does not detect the gamepad correctly?

Have you seen the bit at the very bottom of:
wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_Remote_Pendant
Where it mentions having to fiddle with the plugdev rules? Your problem might be related to that.
There are some more details at the bottom of the manpage too:
www.linuxcnc.org/docs/html/man/man1/hal_input.1.html
You might end up having to look around the Internet for further information, maybe googling for raspberry and udev together.

Hello andypugh,
thanks for your response.
I already tried the entries in /etc/udev/rules.d. It does not solve the problem.
In the meantime I tried to use the gamepad with a standard Raspbian installation. The device gets installed correctly without any problems (/dev/input/js0).
On Raspbian the following modules get loaded:
Copying the files in /etc/udev/rules.d from Raspbian to LinuxCNC does not change anything.
I also tried to add the group 'input' to LinuxCNC and assigned the user pi to it. No effect.
When I try to load the above mentioned modules manually on LinuxCNC, I get a failure when trying to load hid_dr:
When I understand it correctly this should be the driver for this gampad (even so it seems not to be used in the Raspbian standard installation).
So the next step would be to get this module running with LinuxCNC, but at the moment I do not understand why this module is not available. I thought it should be included in the LinuxCNC built.

I've solved the problem. The missing kernel module for the DragonRise gamepad caused the trouble.
After compiling the Xenomai kernel with the driver support the gamepad is working now.
