force feedback wheel usb


hello, i am trying to get a force feedback steering wheel working under slackware 10. i am following this:

http://www.charmed.com/txt/force-feedback.txt

here's the start of it breifly:

At the kernel's compilation:
- Enable IForce/Serial
- Enable Event interface

then enable the following modules
% modprobe joydev
% modprobe serport
% modprobe iforce
% modprobe evdev (i ignore the line after this one as its just for serial devices)
i do all these in the /etc/rc.d/rc.modules

i basically ignored the stuff about the kernel, did the second part and since the modules load fine i presume they were already in the kernel.

i managed to get a normal analogue joystick working for a driving game fine (but i'll hopefully be able to beat my brother if i get this steering wheel working ), but i re-commented all its modules and put the above modules into a separate single section within rc.modules. just to keep it tidy, i.e.:

### Thrustmaster Force Feedback Wheel (I-Force) module section:
/sbin/modprobe joydev
/sbin/modprobe serport
/sbin/modprobe iforce
/sbin/modprobe evdev

& from dmesg i find the following lines:

usb.c: registered new driver iforce

hub.c: new USB device 00:07.2-1, assigned address 2
iforce.c: info ( cmd = ff01, data = 43 )
iforce.c: info ( cmd = ff03, data = 45 00 01 )
iforce.c: info ( cmd = ff01, data = 4f )
iforce.c: info ( cmd = ff04, data = 56 02 05 00 )
input0: Guillemot Force Feedback Racing Wheel [20 effects, 1000 bytes memory] on usb2:2.0

and even within KDE > System > Info Centre it picks up 'Guillemot Force Feedback Racing Wheel' under the USB Devises section. i know the wheel is an i-force compatible device.

i have also downloaded fftest but it does nothing when i select a force to 'play' on it. even when running ./fftest /dev/input/event0 -g 100 (i tried a few different event devices), which is the maximum force setting.

can anyone help, or have managed to get this to work?

PS: quick samba question; winxp-home ics (hdcp) router, but that pc gets used as 'admin' user. the password requirements in samba are annoying when the winxp pc tries to browse this linux pc, is it possible just to disable them, i dont want to limit the access like this.

ive checked the default kernel .config that comes with the slackware 10 2.4.26 kernel and the above ones are all available to load.

oh, and also whenever i reset the computer the wheel brings its forces back on but when it gets to the rc.hotplug bit the forces go off again. i tried removing rc.hotplug only to stop my usb mouse working.
