Note: the above may not be strictly true anymore. It looks like Validity is trying to maintain universal driver which supports all hardware.
Same seems to be true for the .xpfwext files. I.e. the firmware file may not be very platform specific, however the firmware file
must match the version of the Windows driver which contains the command/configuration blobs. Because we extract these blobs
from the actual driver DLL and logs, `python-validity` relies on a specific version of the firmware file. At the moment I can confirm
that `python-validity` works on both vfs009a and vfs0097 with a firmware file `6_07f_lenovo_mis_qm.xpfwext`
(sha1 `edb295cc26a259ec54fef86646d1225f65bb6b80`).

## DBus service ## DBus service
Sources contain a simple DBus service which can impersonate [fprint](https://www.freedesktop.org/wiki/Software/fprint/) daemon. Sources contain [dbus-service.py](dbus-service.py) file, which is a simple DBus service which can serve list/enroll/verify/delete prints.
Install fprint, edit /usr/share/dbus-1/system-services/net.reactivated.Fprint.service by commenting out activation info: Previosly it was trying to impersonate [fprint](https://www.freedesktop.org/wiki/Software/fprint/) daemon.
``` Right now it owns it's personal DBus name `io.github.uunicorn.Fprint` and implements a slightly different interface.
#Exec=/usr/lib/fprintd/fprintd
#User=root
#SystemdService=fprintd.service
```
start a fake service with something like this:
```
while sleep 1; do
python3 dbus-service.py
echo "====restart==="
done
