[fprint] Digital Persona 138a:0005

[brian@amason.net]

Well, I downloaded version 0.4.0 and the latest fprint-demo. fprint-demo
doesn't see the fingerprint scanner.

However, running the example codes I get this when trying to enroll or
verify-live.

$sudo ./enroll
Found device claimed by Validity VFS101 driver
Opened device. It's now time to enroll your finger.

You will need to successfully scan your finger 3 times to complete the
process.

Scan your finger now.
vfs101:error [async_recv_cb] transfer not completed, status = 6
async:error [fpi_drvcb_enroll_stage_completed] BUG at async.c:161
sync:error [fp_enroll_finger_img] unrecognised return code -5
Enroll failed with error -22

Now it says VFS101, but I left the code alone and added the VFS301 to the
list of supported devices for the driver.

$ diff vfs101.c vfs101.c.new
1542a1543
>       { .vendor = 0x138a, .product = 0x0005 },

------------------
The other examples gave other messages.

$sudo ./img_capture
Found device claimed by Validity VFS101 driver
Opened device. It's now time to scan your finger.

image capture failed, code -95


Verify failed because the was no file to verify.

cpp-test seems to do nothing, but no error.

That's all for tonight (morning). I'll have to dig into the code to see
what the messages mean.
