Oops!  I apologize for missing that information.

Laptop Model:  HP ENVY dv6t-7300 CTO Quad Edition Notebook PC

Here is what I get from lsusb.

I believe the fingerprint reader is the one made by Validity Sensors, Inc.

Here is the verbose output.

That's useful, but what doesn't work? Does the kernel module for the
sensor load (check the output of "dmesg" and "lsmod")? Is the
fprint_demo not working? Can't you enroll any prints?

Just saying "help me get it to work" is rather vague. We can't help
unless we know what's broken.

    I suggest you mention what model of laptop you have, or at least
    what the sensor hardware is. You might also be more specific about
    what "not working" means.
