USB Fingerprint Reader
I compiled the Linux and the libraries to use the fingerprint reader. The Linux kernel is 18.104.22.168 and the libraries installed are glib2, openssl, libusb and libfprint. The problem is that the library don't find the connected reader. I need to add something to the kernel? I search for such option in Device Drivers -> USB Support in the 'menuconfig' utility, but I didn't find anything.
Does someone has any suggestions?
First of all: Is this LFS related or are you doing this in Ubuntu? If this is not done in LFS, ask a moderator to move this thread to the Ubuntu (or hardware) sub-forum.
I do think you need to give a bit more information: Which fingerprint reader are you talking about (brand and type) and which (if any) documentation are you following?
You might indeed need an extra kernel option, if there is one for your specific device.....
Hope this helps.
No, I'm not trying to do this in Ubuntu. I used it only for compile the kernel and so. By the way, I used Buildroot to create the images - the system is running in a ARM9 board. I'm trying to use the Digital Persona U.are.U 4000 USB fingerprint reader - that's supported for libfprint. I've already tested the device in a PC, both in linux and windows. During the compilation of the libraries and dependencies, all went ok. I developed a simple console program to test the functions of the library, and it compiled and run alright, but didn't find the reader - for this reason that I think that is something missing in the kernel config.
