I have an HP dv4 2080br with a fingerprint reader that works fine on Windows 7.
lsusb lists it as
Bus 001 Device 004: ID 138a:0005 DigitalPersona
How can I use it on Ubuntu 10.10?

There is a packaged called fprint available in this PPA However, it does not appear that your device is listed as "Supported". There is a bug Bug #285089 Which details issues with a similar USB device id though I don't believe it is related nor confirmation that this device does not work with the fprint package.
try this! searched for around 5 months trying to get mine to install..... you WILL find one of the three will work. https://launchpad.net/~fingerprint as far as which one will work... well thats trial and error
Assumed that you are using Ubuntu 12.10.
printd packages from universe.
$ sudo apt-get install libpam-fprintd fprintd
You should see the following.
$ grep fprint /etc/pam.d/common-auth auth [success=2 default=ignore] pam_fprintd.so
Enroll your fingerprint.
For additional security you may want to use only password to log in to the desktop. Then do the following.
$ sudo cp /etc/pam.d/common-auth /etc/pam.d/common-auth-nofinger $ sudo vi /etc/pam.d/common-auth-nofinger
/etc/pam.d/common-auth-nofinger. Remove the line
auth [success=3 default=ignore] pam_fprintd.so
and save and quit.
$ sudo vi /etc/pam.d/lightdm
/etc/pam.d/lightdm (or /etc/pam.d/gdm, if that's what you're using) so that it "@includes"
/etc/pam.d/common-auth-nofinger rather than
