My mistake, started with "VFS", and filed at about the same time, my brain didn't parse it all.

I can confirm this bug.

I tested with libfprint 0.4.0, normal and with vfs301 patch from Andree


https://github.com/andree182/vfs301/tarball/master


I added to that driver the 138a:0007, the fprint_demo detects it but does not work.

Confirmed bug on Hp 2540p notebook. 
Bus 001 Device 005: ID 138a:0007 Validity Sensors, Inc. VFS451 Fingerprint Reader

Is it available as a standalone USB device? Any chance to get logs captured by USBSniff under windows? See http://www.freedesktop.org/wiki/Software/fprint/libfprint/USB%20sniffing

If needed, I can provide usb sniffs about it.

It would be nice

capture trace with usblyzer

I have added a trace, if it is not valid or you need more of them, please tell me as fast as you can, because I am doing it with USBlyzer, which is free for 30 days...

Hope it helps, looking for fast ACK :D

Please capture at least 3 sniffs with similar conditions, i.e. start capture on _clean_ boot, do capture of same event. Need them to analyze what part of traffic changes

Dear Sender,

I will be out of office till 3rd Dec and will have very limited access to my emails. For urge matters pls email to;

dgfemabuit@dhl.com

For "very" urgent matters pls call me fm my mobile; +90 533 502 3090

Hi, I own a device with this reader and would like to help to get it supported. I am not a developer, but capable of entering console commands, testing an output, modifying a config file, compiling in a kernel module. I could also create a clean account that a developer could tunnel into if that helps. Let me know if i can help.

Hi Andreas,

As I already said, it's close to impossible to develop a driver without device available at hands. But I can guide someone who want to develop driver for libfprint.

Same here, elitebook 8440p

Roughly how much effort would it take to make this driver?

Dear Sender / Colleague,

You will receive this Out of Office notification only once.

I will be out of office between 15/FEB - 18/FEB due to biz travel and will have limited access to my emails. There might be some delays for my replies. Resume to work on 19/FEB.

For "very" urgent matters pls call / text me fm my mobile

Depends. If protocol is not encrypted and device doesn't require any fancy handshake, it takes 2-3 days for me.

I have a laptop with one of these devices and am thinking about either volunteering for instruction or mailing it to you for you to do it. I assume reverse engineering the device won't require destructive modification of it?

Usually I use VM with Windows in it and Linux host with wireshark to capture USB traffic. So it doesn't require any hw modifications at all.

I have one of these fingerprint readers.

conor@Lappy:~$ lsusb | grep Validity
Bus 001 Device 004: ID 138a:0007 Validity Sensors, Inc. VFS451 Fingerprint Reader


In an HP Elitebook 8540w.

I have never developed drivers before, but If USB captures would help in any way I can provide them.

What conditions would need to be sniffed?
