Linux-friendly USB fingerprint reader?

Has anyone here had success with USB fingerprint scanners? I also found this Microsoft keyboard with fingerprint reader but I don't know if it works with linux.

Biometrics, huh? You know- passwords are more secure...
- For simple PC unlocking etc. they are perfectly fine and improve security due to their far higher usability.
  The same way 10 key files on 10 different locations combined with this and that are more secure than a simple 60 character password. But the simple password is far more practical, so far more secure overall since people actually use it.
  
  It's easier to steal, copy, or alternatively subpoena a fingerprint.
  
  For most people, the only security they really need is against people either stealing devices or accessing them without permission. In those cases, biometrics (if implemented properly) and passwords are roughly equivalent.
  
  This is why we have duress passwords.
  
  "we" as in absolutely not most people.
  
  Just people who include "getting beaten with a wrench by my adversaries" in their threat model
- More secure legally. You generally can't be compelled to disclose a password that incriminates you (unless it's already apparent that you're guilty of wrong-doing) but a thing (physical key, fingerprint, etc) isn't protected in the same way and can be demanded by the court.
  Whether biometric are secure or not is another question, they can be stolen like any other data or a motivated attacker could just take you or your fingers.
  
  You can use a piece of tape to get a fingerprint off the case of the device. No it is not as secure as a strong password
- Biometrics plus a password is even more secure.
- I'm not sure why the down votes. You are completely right
  
  They didn't ask for security advice, though...
