HID: force feedback support for SmartJoy PLUS PS2/USB adapter
Jussi Kivilinna [Wed, 13 May 2009 08:54:38 +0000 (11:54 +0300)]
This driver adds force feedback support for SmartJoy PLUS PS2/USB adapter. I
made this driver one device spesific instead of making generic 'wisegroup-ff'
because I have another Wisegroup PS2/USB adapter that doesn't work same way as
SmartJoy PLUS. If another device that is compatible pops up, this driver could
be then renamed to something more generic.
