 |
|
Hi everybody,
since my upgrade from kernel 2.6.29 to kernel 2.6.30-r5 there is no /dev/input/js* anymore.
| Code: |
# dmesg | grep -i Joystick
generic-usb 0003:06A3:0255.0002: input: USB HID v1.00 Joystick [Saitek Saitek X52 Flight Control System] on usb-0000:00:1d.0-2/input0
# ls -l /dev/input/by-id/*event-joystick
lrwxrwxrwx 1 root root 9 Aug 26 2009 /dev/input/by-id/usb-Saitek_Saitek_X52_Flight_Control_System-event-joystick -> ../event4
|
The hardware seems to work correctly as
| Code: |
# cat /dev/input/event4
|
gives me some output.
If I choose kernel 2.6.29 udev makes a /dev/input/js0 correctly.
Can anyone help me to get my joystick working again? |

It seems as though the only problem is naming convention for the joystick's /dev file. Maybe you could symlink to it, or maybe you could create a new device with the same major and minor numbers with mknod.

hi erik258,
i tried:
| Code: |
# ln event4 js0
# jstest js0
Driver version is 0.8.0.
Joystick (Unknown) has 2 axes ( axismap never defined )
and 2 buttons ( buttonmap never defined ).
Testing ... (interrupt to exit)
jstest: error reading: Invalid argument
|
and also
| Code: |
# mknod js0 c 13 0
# jstest js0
jstest: No such device
|
Still if I just switch to Kernel 2.6.29 it creates the /dev/input/js0 device. Do I have to change some kernel options in 2.6.30? |

Solved!
In recent web searches I found that there is a kernel bug that doens't accept the "Saitek X52" as a joystick.
I changed the kernel source /usr/src/linux/drivers/input/joydev.c according to this bug:http://bugzilla.kernel.org/attachment.cgi?id=23054

After that my /dev/input/js0 appeared again. This bug is in the kernel since version 2.6.30.
I upgraded to 2.6.32 by now and still have to change the kernel code in joydev.c
I hope this might help all SAITEK X52 Flight Control System users. |
