USB Overdrive Updated to Beta 4

USB Overdrive beta has been released, bringing it to version 4. USB Overdrive is a USB device driver designed to add more functionality to devices including mouse and trackballs. The latest version ships with performance enhancements including AutoScroll support and a System Pref shortcut. According to Alessandro Levi Montalcini:

The fourth Mac OS X public beta of my USB Overdrive mouse and joystick driver is now available. This beta is for Mac OS X 10.1.2 and later and only supports mouse and trackball devices.

The final version of the USB Overdrive X will soon be distributed as shareware through Kagi. Users of the Mac OS 9 version who registered after the release of Mac OS X are entitled to a free upgrade using the same code they already received.
