How can I use the fingerprint reader on my HP DV6-3049TX?
I've tried it with some software (please edit so we know what you've tried) but it just says "No device".
There's a similar question asked here:

This comment: FPrint - points out a software that could help you, it has a list of supported devices, but aparently your laptop is not in the list. Nonetheless I would give it a try
lspci
andlsusb
so we can see what the fingerprint reader we're dealing with here is.
