Don't expect help from Logitech unless an employee is a friend there. Maybe someone can reverse engineer windows drivers or sniff the usb. I have usbtool mirrored on my site: http://richieward.com/files/usbtool-0.1-compiled.tar.gz People should make more mirrors. I made some of that into a bash script (run script as root): #!/bin/bash ./usbtool g25-set-extended-mode sleep 1 ./usbtool g25-set-range-wheel-900 sleep 1 rmmod joydev sleep 1 rmmod usbhid sleep 1 modprobe usbhid some ff attempts: richie@richie-desktop:~/Downloads/ff-utils$ sudo ./ffcfstress -d /dev/input/js0 ERROR: can not get key bits (Invalid argument) [ffcfstress.c:118] richie@richie-desktop:~/Downloads/ff-utils$ sudo ./ffcfstress -d /dev/input/by-id/usb-046d_G25_Racing_Wheel-event-joystick ERROR: device (or driver) has no force feedback support [ffcfstress.c:165] richie@richie-desktop:~/Downloads/ff-utils$ sudo ./ffcfstress -d /dev/input/by-id/usb-046d_G25_Racing_Wheel-joystick ERROR: can not get key bits (Invalid argument) [ffcfstress.c:118] On Tue, May 13, 2008 at 4:15 AM, D.
