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.

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
