Subject: [PATCH] usb: PlayStation 2 Trance Vibrator driver
Newsgroups: gmane.linux.usb.devel
Date: Wednesday 30th August 2006 00:34:56 UTC (over 11 years ago)
This patch against 2.6.17.8 is a driver for the PlayStation 2 specific
Trance Vibrator device. The only thing that device can do is vibrate at
various speeds.
