I'm trying to read from a USB analogue joystick, and have got as far as:
{dawson}halej: jstest /dev/js0
Joystick (Saitek Cyborg 3D Rumble Force) has 7 axes and 12 buttons.
Driver version is 2.1.0.
Testing ... (interrupt to exit)
Axes: 0:-32767 1:-32767 2: 0 3: 0 4:-32767 5:-32767
6: 0 Buttons: 0ff 1ff 2ff 3ff 4ff 5ff 6ff
7ff 8ff 9ff 10ff 11ff

The joystick type is detected correctly (its a USB joystick) but I can't
get any data, i.e. moving the stick, pressing the buttons etc. doesn't
work. I loaded the joydev module, and the analog module before I could
get any response from jstest.
Linux 2.4.18 #2 Tue Feb 26 12:07:22 GMT 2002 i686
I'm running redhat 7.3.

So, any suggestions for getting some feedback from the joystick?

Thanks,

Josh.

4 buttons connected to the 15-pin gameport."
Well, the device exists, which is a good sign.
Every USB joystick I've heard of/seen out there uses the "hid" module,
not the "analog" module. You need to have the following modules loaded
for most USB joysticks to work:

usbcore
usb-uhci (or usb-ohci)
joydev
input
hid

The docs in /usr/src/linux/Do***entation/input/joystick.txt say that
many Saitek joysticks are supported by the analog module, but since this
is a USB device, it should be handled by hid, unless this joystick was
designed by crack-smoking monkeys.
Hm. The hotplug daemon should've loaded hid automagically when you
plugged this device in. Unplug the joystick, plug it back in again, and
do "dmesg | tail -20" right after plugging it in again, then post the
output.

Hi dude,

Thanks for the response... I checked all those modules that you
mentioned and they are all loaded:

usbcore
usb-uhci
usb-ohci
joydev
input
hid


So I plugged it in and out, ran dmesg and got the following... (about
ten million disk change events which seems a bit odd...?)

VFS: Disk change detected on device ide1(22,0)
VFS: Disk change detected on device ide1(22,0)
usb.c: USB disconnect on device 2
VFS: Disk change detected on device ide1(22,0)
VFS: Disk change detected on device ide1(22,0)
VFS: Disk change detected on device ide1(22,0)
hub.c: USB new device connect on bus2/1, ***igned device number 3
VFS: Disk change detected on device ide1(22,0)
VFS: Disk change detected on device ide1(22,0)
VFS: Disk change detected on device ide1(22,0)

Whats your verdict?

Josh.
