my fresh installed fingerprint-gui stucks when I try to register my fingers. The first scan gives a green tick, but when the program asks me to repeat the step the scanner wont scan it. Normally the scanner blinks green when reading, but not after the first swipe... The used scanner is from a Thinkpad T440,

the Ubuntu Version is 15.10 and the system is up to date. Here is a detailed erorr Log:

Where is the problem, or more specific what means error -22? I haven't found any error->meaning list for fingerprint-gui...
The rest of the progam seems to work, the fingerprinter always blinks when auth is needed and only shows the error that it was unable to open the folder with the stored fprints (because there is no such folder since no finger was stored sucessfully...)
ingerprint-helper[3182]: Could not open /var/lib/fingerprint-gui/wucke/vfs5011/
So, thanks for any tips, suggestions or advices...
