[Libff-devel] Wingman Force 3D in linux, not only questions.

Hi,

I'm sorry for bothering You, I hope it is the right list. So fat I read mos=
t=20
of it's history, and I guess (almost) all of what is related to logitech=20
devices.

I have Logitech Wingman Force 3D and I'm interested in getting to know how =
to=20
use it in own programs, also I think I could help in driver and library=20
development. Earlier I thought I have problems making it work, since only=20
"constant force" in fftest was giving a (hardly) noticable effect. Correct =
me=20
if I'm wrong, but is it the only effect implemented for this joystick (at=20
least at the moment) ?

If it is not (and I have done something wrong), first of all, my system:
Linux gentoo using 2.6.11 kernel (gentoo-sources-2.6.11-r6 - it has later=20
patches - 2.6.11.x applied)
gcc 3.4.3-20050110 (Gentoo Linux 3.4.3.20050110-r2, ssp-3.4.3.20050110-0,=20
pie-8.7.7)

uname -mo
x86_64 GNU/Linux
(but have tried on x86 as well, same effect)

In the kernel I have:

Whe I connect joystick dmesg shows:

I started learning how to communicate with the device, I have c++ class=20
"Joystick" written mostly using HID howto. For now it can only read positio=

from the device (periodicaly, in separate thread), output some information=

however when it will be closer to the desired result, I think it could be=20

I would be interested in adding (or helping to add) better support for=20
Logitech Wingman Force 3D (since it is the device I have at the moment).=20
Do You have any suggestions for beginner (not in programming, but in revers=

engineering) on how to find joystick's abilities (and how to connect them t=

specific commands)

Below a little more detailed version of what I can see using ffutils.

so I guess it's ok, but than I tried fftest, what I see after running it
# fftest /dev/input/event4

when I press 1, I get hardly noticable change in joystick force, but no oth=
