I just released VueScan 7.1.19 for Windows, Mac OS 8/9/X
and Linux. It can be downloaded from:

What's new in version 7.1.19
* Added USB support for Microtek X12USL, 4700, 8700
* Added FireWire support for Microtek and Polaroid scanners
* Fixed bugs with some Microtek and Polaroid scanners
* Increased default white point (%) from 0.5% to 1%
* Slightly changed "Color|Gamma" so it affects the image
similarly to the way "Color|Image brightness" did in 7.1.16

Ed Hamrick
