c9ff2c5541 Add Veridicom 5th Sense driver
Based on bus traffic analysis of the windows driver. This device is
working well, but finger presence detection is not yet implemented.

617ca8cd15 fix imaging action state for repeated enroll attempts
Enroll attempts may retry in some situations, so we need to reset the
state to accept more scans.

a11ac7d8f8 uru4000: search for encryption byte
New DigitalPersona devices have a new firmware. We now use a search
scheme to find the encryption byte, by examining known locations
in the firmware until we find something that we recognise.

81a5d6d966 Only use -fgnu89-inline when supported
This only works for GCC 4.3 and newer. GCC 4.2 and older already have
the semantics introduced by using this argument.

07a42d5f91 uru4000: Retry initialization 3 times
Sometimes we don't get the powerup interrupt, so retry the whole process
up to 3 times if we time out waiting for the interrupt.

88e9f4a5f8 Public async API implementation
Involved some internal overhaul/reorganisation. Nice side effect is that
the synchronous API is now expressed purely in terms of the public async
API.

754e56aec1 Allow execution of sub-SSMs
A subssm will be executed, and upon completion the parent state machine
will either be advanced to the next state or aborted with error, depending
on the outcome of the subssm.

Also add some debug messages.

866dd941cc Add timing and polling infrastructure
Add timeout mechanism as an asynchronous equivalent of sleeping (uru4000
needs this).

Start implementing polling infrastructure which also accounts for pending
timeouts. We don't expose file descriptors yet, but this is a start.

bf7093d607 Port to libusb-0.9.0 (synchronous I/O)
Straightforward port to libusb-0.9.0 sync I/O functions, to give libusb-1.0
a bit of a test drive and to create a reference point for later.

6f456f399d Add Secugen FDU2000 driver
[dsd@gentoo.org: some trivial changes:
fixed some warnings
fixed fp_img memory leak on error
renamed endpoint constants (calling a bulk endpoint 'ctrl' is confusing,
as a control endpoint is something different)

642010643d uru4000: Add support for Microsoft Fingerprint Reader v2
After lot 713, Microsoft fingerprint readers changed. The new version
comes with a new USB product ID and a challenge-response authentication
scheme where the device challenges the authenticity of the driver.

An independent third party produced documentation on the computations
needed to convert a challenge into the correct response, and I then used
this documentation to produce a clean-room reimplementation of the
authentication scheme.

8e0e8e4386 aes1610: imaging improvements
bz threshold is now 10 (instead of 15). I think it is ok for the moment.
If we manage to get higher image quality in the future, we'll change that.

max_frame is set to 350. 150 was too low => incomplete fingerprints

the driver was designed to stop the acquisition as soon as it gets a blank
frame (=> incomplete fingerprints). Now it waits to have at least 50 blank
frames before stopping.

c5a550e42c Add Authentec AES1610 driver
This is an active capacitance swipe-type device similar to but smaller
than the AES2501.

Image processing performance is good but matching performance is not so
good. The bozorth3 matcher needs tweaking in order to better cope with
small sets of minutiae.

With a lowered threshold, matching performance is good enough for now.
