Hello everybody. I would like to develop a driver for any kind of fingerprint reader that currently doesn't have a driver for linux, and I'm open for suggestions on which device I should use. My first thought was the microsoft usb fingerprint reader (http://www.geeks.com/details.asp?invtid=DG2-00002-DT&cpc=SCH) because it's a new device (and, of course, doesn't have any driver for linux), it's cheap, and it's from MS (read "would be fun" =) Before proceeding, I would like to know if: 1) Would it be ilegal to write a driver for such device (i.e., without the permition of the hardware manufacturer) ? 2) Is there any standard on how the fingerprint should be presented to userspace ? Currently the only fingerprint driver that I could find is the Siemens ID Mouse driver (drivers/usb/misc/idmouse.c), and it delivers the fingerprint as an image in pnm format thru a device like /dev/idmouse0 (cat /dev/idmouse 0 > /tmp/fingerprint.pnm). Is this the best way to deliver the image to userspace, or should we have an centralized for that, or a centralized device like /dev/fingerprint0 (which then wraps to the idmouse driver or any other) There are also other interesting devices like this (http://www.geeks.com/details.asp?invtid=FIN002&cpc=SCH) that are cheap and probably would be a better subject. I know that there are some standards (something related to the resolution of the readers), and some of the cheap ones don't meet some "high-profile security" standards (I think from NSA or something like that). Maybe we should also try any of those heavy-duty high-security gadgets too. Another question: Is there any place (probably a webpage) where we can see a list of hardware devices separated by category, and know if there's already a driver for it (and the name/url of the maintainer) or not, if there are plans to develop a driver for it or not, or to form teams to develop it ? Like a webpage where I can browse and see that the device X doesn't have any drivers for it (and people can go and "vote" for a driver, so we can know which devices are most wanted by users), and sign ourselves to develop it ? I think that it would be cool. If there isn't anything like that, I can develop it myself and somebody at kernel.org or another place could host it =] Thanks, Daniel -- What this world needs is a good five-dollar plasma weapon. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
