Indeed. The udev rules generator was too smart: your device is blacklisted by libfprint for the power/control capability so there was no udev rule created at all. The attached patch embeds the Debian-specifics in that udev rules generator while respecting the blacklist for power/control. This will be uploaded soon. > SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="2015", > ATTRS{dev}=="*", ATTR{power/control}="auto", MODE="0664", GROUP="plugdev" > SUBSYSTEM=="usb", ATTRS{idVendor}=="1162", ATTRS{idProduct}=="0300", > ATTRS{dev}=="*", ATTR{power/control}="auto", MODE="0664", GROUP="plugdev" > > Maybe this readers can be added to the rules file from libfprint0? No; and here's why: 0483:2015 and 1162:0300 are devices supported by the "upektc" and "fdu2000" drivers respectively. These two drivers cannot currently be compiled in libfprint and are marked as "not ported" (to libusb-1.0). So before adding the udev rules for them, one needs to port the drivers. Cheers, OdyX
