- added a [lame] way to cancel an active capture
- detect when usb device is disconnected (seems to work fine with suspend/resume)
- try to gracefully end dbus service when device is disconnected
- make TLS session persistent:
once open, you can save TLS state with tls.save() and
restore it next time by calling tls.load() instad of tls.open().
State is saved in tls.dict file.
- a small standalone script added which can be used to keep an open
file descriptor to the device. Without it tls.load() wont work.
- identify() function added
- added methods to associate blobs with fingers. Windows seems to be
using these blobs to save certificates for the users to establish
trust with potentially removable devices (it is sort of documented in
winbio specs)
