This gamepad works beautifully in Linux from 2.4.20 kernels with the appropriate USB drivers. You will also need the joystick tools (almost all distributions have them). It works plug & play almost perfectly, except for the rumble features which do not work, also reason why I rate it with a compatiblity of 9, because despite the fact that all axes and buttons work, the rumble feature is still missing. I havent tried those with the added HID extensions to the 2.6.x kernels, though. Ideal to play games in applications such as X-MAME, PSX emulators (ePSXe, PCSX), N64 emulators and other games. In order to be used the driver joydev must be loaded!
