Linux

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I use the DigitalPersona 4500 with libfprint. Unfortunately, there are multiple revisions of the device with the same model number and only some of them work properly under Linux (different encryption method I believe). As far as I know this is not actually documented anywhere. Googling just shows a bunch of unresolved bug reports of people having no idea why it doesn't work.

Bus 001 Device 059: ID 05ba:000a DigitalPersona, Inc. Fingerprint Reader

It shows up exactly the same for all the revisions though.
