Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

[invitu (invitu)]

you can update your usb and pci ids using :
sudo update-usbids
sudo update-pciids

your lsusb and lspci commands should give better results

[Gargoulf (pasquiernoterdaeme)]

I did those updates. Still same error "device not found"

[invitu (invitu)]

I have same problem with my dell e6410

the goal of "update-usbids" was too show more details in "lsusb" command.
can you check for the model of your fingerprint reader by typing "sudo lsusb"

mine is :
Bus 002 Device 004: ID 0a5c:5801 Broadcom Corp. BCM5880 Secure Applications Processor with fingerprint swipe sensor

For the moment, I did not find any driver for that device. I guess it's the reason why thinkfinger/fprint tools don't find the device

[invitu (invitu)]

I found this : http://natisbad.org/E4300/index.html
it speaks about the smart card reader but I think it can be useful

[Gargoulf (pasquiernoterdaeme)]

Seems I have exactly same device:
sudo lsusb gives:
Bus 001 Device 004: ID 0a5c:5801 Broadcom Corp. BCM5880 Secure Applications Processor with fingerprint swipe sensor

[Gargoulf (pasquiernoterdaeme)]

invitu: In the link you gave, I found:

Fingerprint reader:
"There is currently no support for the device (neither via fprint, thinkfinger, or any other project). Considering that Broadcom does not provide the specs, this will probably require some reverse engineering. "

[Mano (mano-redhat-bugs)]

Description of problem:
 In Dell4300,the broadcom finger reader is not working in F12,F14.

when run fingerprint-gui its says not device found.

I have even raised bug last year for fedora 12, but did not got any response.

[Bastien (bastien-redhat-bugs)]

It's not supported, because Broadcom won't give us specs for it. If you want it supported, you'll have to work upstream to get a driver written.

Maybe now that Broadcom have joined the Linux Foundation pressure could be brought to bear to release the specs for this device as it would presumably bring added security functionality to a whole host of business laptops.

[Gargoulf (pasquiernoterdaeme)]

No progress for 11.10...

[DiegA70 (sanchezcavalieri)]

Hi, is the device working now with the new libfprint?
Thanks.

[Gargoulf (pasquiernoterdaeme)]

just upgraded to 12.04 LTS. Still "no device found" when using fprint-demo

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[spectre (spectre3brad)]

Canonical can not work directly with Broadcom to offer a Linux driver has to leave even one as Nvidia proprietary driver?

When testing or no response Broadcom contact via email or through social networks.

Canonical may have more weight to the application.

Otherwise will have to harass them on social networks and email Lol.

[spectre (spectre3brad)]

I sent requests on accounts Broadcom, Dell, Linux, Ubuntu via email and social networks.

And a forum post Dell [Fr]: http://fr.community.dell.com/forums_daide/logiciels_et_systme_dexploitation/f/76/p/161/288.aspx # 288

I invite you to do the same to get things done, because if we had to request several groups Dell, Linux, Ubuntu will demand has supported Broadcom and we may be I hope finally an answer favorably to our request for a Linux driver.

I provides more every time this thread to bug their offer to come who can give their opinion on the subject and thus transcribe all in the same place more than what is easy.

[Christopher M. Penalver (penalvch)]

Gargoulf, thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of libfprint via https://bugs.freedesktop.org/enter_bug.cgi?product=libfprint . If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

[spectre (spectre3brad)]

Hello, I signal that the chip BCM5880 Broadcom supplied on multiple PCs in my case with the Dell Latitude E6530 and Ubuntu currently unusable because no driver provided by Broadcom for Linux. At the request of a developer Launchpad Linux / Ubuntu so I have to open an thread on the subject to try to get things done.

I invite you to come and read a first time in this thread to see what has been done on our side:

Bug Launchpad: https://bugs.launchpad.net/libfprint/+bug/602071

Thanking you in advance for your help.

[spectre (spectre3brad)]

I went created a bug report upstream as I am in the same case. Waiting for response.

https://bugs.freedesktop.org/show_bug.cgi?id=56752

[Mike Simpson (mikie-simpson)]

I think it is more complicated than the usual device that fprint is used for as it is not a straight fingerprint scanner but is a multimodality identity authenticator. As Broadcom joined the Linux foundation a while ago I had hoped that someone with enough clout could have asked them for the specs before now. It is like their wifi cards all over again. It is the only part of my dell E4200 that doesn't work in Linux

[anarsoul (anarsoul)]

Is it available as standalone USB device?

[anarsoul (anarsoul)]

Can you provide logs produced by USBSniff? See http://www.freedesktop.org/wiki/Software/fprint/libfprint/USB%20sniffing

[spectre (spectre3brad)]

I received an answer that day an employee responds Broadcom me this:

"Hi,
Thanks for your mail.
I Understand That this Dell machines only ships with Windows OS. If you want to mount other OSes, you'll Have to Directly Contact Dell for support.

Regards,
Jason
Broadcom Corporation "

So I answered this:

"Hi, The Machine est aussi sold via Dell Ubuntu Linux. Aussi I Asked Them for help on this topic It Seems That goal They Have not Heard even from this side and That is why I come directly to Broadcom to make a request for publication of a pilot for the Linux product. This is a strong demand in the community.

I Asked a Dell, Linux, Ubuntu and Canonical libfingerprint who Seem em even Have No solution so far. It Seems That only the creator Broadcom chip can help us on this issue.

Hoping to Have a positive response from Broadcom icts for customers.

Good day and thank you for your help. "

I invite other applicants pilot to request a Broadcom and PC vendor (Dell, Asus ...) to try to get things done. The higher the demand will be stronger and we will get the chance to pilot and highlight the growing community of Linux.

[spectre (spectre3brad)]

Hello,

for the procedure it seems that we must activate and deactivate and then reactivate the USB concerned?

Only the integrated fingerprint and direcement the laptop so no physical access to turn on and turn off the USB bus concerned.

How to proceed?

Thank you.

[Mindaugas B. (embar-super)]

I just hope, that descriptions in drivers for Windows could help to implement drivers for linux.

[Christopher M. Penalver (penalvch)]

Mindaugas B., unfortunately, it's not helpful at all. However, what would be helpful is creating the USBSniff logs requested by upstream in https://bugs.freedesktop.org/show_bug.cgi?id=56752 .

[Mindaugas B. (embar-super)]

in https://bugs.freedesktop.org/show_bug.cgi?id=56752 link to http://www.freedesktop.org/wiki/Software/fprint/libfprint/USB%20sniffing does not work. I suggest it was instruction to usbmon.

[Mindaugas B. (embar-super)]

usbmon log then opening fingerprint-gui and one minute later pressed "Rescan"

[Mindaugas B. (embar-super)]

reset with http://www.roman10.net/how-to-reset-usb-device-in-linux/ instructions

[Mindaugas B. (embar-super)]

I don 't know, if it helpfull, but maybe it is true, that fingerprint device originally is made by UPEK/Authentec, but you can not control it directly because of Broadcom USH layer?

http://forum.notebookreview.com/dell-latitude-vostro-precision/413346-dell-new-fingerprint-reader-owners-must-read-broadcom-ush-issue-effecting-preciosn-m4400-m6400-latitude-e6400-others-6-print.html says:

<...>
On Dell E-series laptops the fingerprint sensor is connected via proprietary interface from Broadcom and UPEK/Authentec driver cannot communicate with the device at all. The driver cannot see the sensor - it is "hidden" behind the Broadcom chip :-(
<...>
I could REM out a line of code or two in INF file of the fingerprint sensor device
Well, I would love to have a complete information about that ;-) But frankly speaking I don't see any logical reason why to do this. Even if you modify the VID and PID list in the Broadcom driver INF file, it simply cannot start working with the fingerprint reader. It's like if you want modify your video drivers to control your printer ;-) Broadcom coprocessor and our fingerprint sensor are completely different devices, each of them requires a different driver. Furthermore, as far as I know, the fingerprint reader is not enumerated by the system at all.

I went through the whole forum thread and the only guy who was close to some solution was the one who disassembled the fingerprint reader device. If this would be connected directly to the USB (to bypass the Broadcom controller) then the fingerprint reader will be normally enumerated by the operating system and it may work correctly. I deliberately use may, as the firmware of TCEFA1FH is designed for use with Broadcom only - it does not support some of the more advanced USB features (my understanding is that these are primarily related to error recovery). Furthermore the TCEFA1FH requires 3.3V, while standard USB provides 5V, so you will need to use some adapter to change the voltage. For "real" USB applicatons we recommend the TCEFB1. Anyway, I do not recommend you to do such hardware modifications!

Please note: The BCM5880 firmware update process contains 2 protection mechanisms to prevent unauthorized updates.

Protection Mechanism 1: TPM Deactivation.

If the Trusted Platform Module (TPM) on the target computer has ever been activated in the past, in order to update the BCM5880 firmware, the TPM must be set to ON and DEACTIVE in the BIOS SETUP program before the firmware update will run. If the TPM on the target platform has never been activated previously, then this step is NOT necessary.

Protection Mechanism 2: Anti-Hammering.

The BCM5880 is equipped with Anti-Hammering protection that detects large numbers of read/write requests in a short period of time. This mechanism protects against malicious software that attempts to gain access to stored credentials by using multiple retry methods such as dictionary or brute force attacks. If a large number of read/write attempts are detected, the BCM5880 will temporarily shut...

[exzR (exzr)]

no other news? i have to recycle this fingerprint reader?

[exzR (exzr)]

i see that dell give and ubuntu 12.04 iso for dell e6540 that include fingerprint reader driver.. it is true?

[Anbu (anbu-s)]

Any update on this? This still doesnt work for me with gnome ubuntu 15.04

[Jozef Wagner (jozef-wagner)]

This seems to be fixed in Fedora, see https://copr.fedoraproject.org/coprs/dani/ccid-drivers-backport/

[Mindaugas B. (embar-super)]

@Josef, mentioned Fedora fix is for smart-card reader, not fingerprint reader.

[ComBin (combin)]

Hello! On 16.04 don't work too.

[Marcin Szałowicz (lolek)]

Bump, this fingerprint reader is also available in e5470, any progress regarding this?

[Pavel Karoukin (pavelkaroukin)]

This also affects Dell Precision M7710, except USB ID "0a5c:5834"

[Davide (davemann)]

Problem persist.
Do someone already tried to use windows drivers converted with ndiswrapper?
I downloaded the software from Dell
http://downloads.dell.com/FOLDER03570999M/2/Security_Driver_WDRHG_WN64_3.3.14.68_A19_01.EXE
and follow this tutorial.
But it's not really clear which files do I have to convert.
Any idea?

[Rob Bruce (r-bruce)]

Dell Latitude XT3 convertible notebook/tablet also uses this device (ID 0a5c:5801 Broadcom Corp. BCM5880 Secure Applications Processor with fingerprint swipe sensor) so is affected by this issue.

[fig_wright (fig-wright)]

I also have this issue with a Dell precision M4500. It's a shame this hasn't been solved in 6 years! :-(

[Michał Skrzypczak (mskrzypczak)]

The same here, Ubuntu 16.04 LTS, Latitude E5470, Bus 001 Device 004: ID 0a5c:5805 Broadcom Corp., not working.

I'd highly appreciate if someone had a look into that!

I have an m6800 with a nice mips fingerprint scanner and ubuntu/gnome 17.10 I would really like ot get it working. Does anyone have any new ideas how to get it working?

It does work and is seen by https://github.com/OpenSC/openct/pull/4

There should be a way to write the driver, the Latitude E6420 has the sensor built in and if you do some hardware hacking then you can monitor the chip's io.

[casas (detodeo)]

Que tal, recientemente hice revivir mi dell latitude e6220 que tenia archivado, estaba con windows 7, instale Ubuntu 18.04 y funciona de maravilla, pero no me funciona el escáner de huellas dactilares, después funciona todo.
