No controller found (linux)

Hello all,

I'm having some trouble running heli-x on linux with any type of usb joystick. I get a "no controller found" error. The KDE joystick panel seems to detect the joysticks well (/dev/input/js0, I've even tested doing a chmod ugo=rwx /dev/input/js0, and it still gives a "no controller found" error), and I can see that the axes move correctly, so the hardware works. The log file from heli-x says;

I'm running kubuntu 7.10 (2.6.22-14 and java 1.6.0_03). If I click OK on the error box then heli-x loads and seems to work, other than my unability to control the helicopter (so graphics/3d works correctly).

If anyone has any ideas I'd be much obliged.

(Unfortunately my german is not very good, so I would prefer english replies if possible).

Running something like 'cat /proc/bus/usb/devices' in a console shows the controller? It's recognized as a joystick?

Hi,

I'd suspect that you're still having a problem due to insufficient permissions. Try a

Code: Select all

chmod o+rw /dev/input/e*
chmod o+rw /dev/input/j*
(changing all events and js's in the input directory to be read- and writable). This shoudl fix (at least) the
console wrote:Failed to open device (/dev/input/event7): Failed to open device /dev/input/event7 (13)
messages. HTH!

Thanks for the help so far, however it still doesn't seem to work.

After performing the chmod operations the errors in the log are gone, however it still can't find any controllers. Log file;

Funnily enough running /proc/bus/usb/ is completely empty, there is nothing there with both controllers plugged in (a logitech gamepad and an E-sky simulator controller), both of which work correctly in the kcontrol program.

Any ideas?

Are you running a 64 bit system? There are typing errors:

Please look in libs\jinput\linux-amd46
Plaese rename it into libs\jinput\linux-amd64

Within this directory there is a file jinput-linux64.so Perhaps it is necessary to rename it into jinput-linux.so

Sorry.

Michael

Hmm, no, I'm running a 32bit system. Relatively standard install.

EDIT: I just tried doing the same thing on another machine (kubuntu 8.04, 2.6.24-17, java 1.6.0_06-b02), and it gave the same error messages. (as before the controller was found by kcontrol and was apparently called /dev/input/js0, so I don't see why it doesn't work.

Could you check your kernel log. Could be something like
less /var/log/messages
or
dmesg | less
The kernel should mention somewhere, that a controller was found and what driver is used for it. Could be, that the gaming lib doesn't support this driver type, but we have to check first, what kind of device your Linux actually recognizes...

/var/log/messages and dmesg both give;

There's an app called 'joystick', that can create the required devices to access your joystick, in case they are missing. There's also an app called jstest, that might help to figure out, where your joystick device actually is...

I tried installing jstest (belonging to joystick) and it seems to output the controller's values for 'jstest --normal /dev/input/js0'. I couldn't seem to find any explicit function for creating devices for the joystick, though it would seem that if it can read /dev/input/js0 that it should work, however I still get the same error when running heli-x.

EDIT: after reading this thread viewtopic.php?f=22&t=11 it would appear that everything should work (I have the e-sky 0905A controller). The reason for it not working is beyond me...
