Having done a search there is an experimental package for the ':55b4' but nothing for the ':55a4'.
I think your only option if it is crucial that you have one is to purchase dedicated fingerprint reader that is compatible with the Linux kernel, but not cheap:
thanks for the help... its a bit annoying that it doesnt work, i ve recently fully moved to linux, im still a begginer but i really like zorin os, i ve had enough with microslop :))) anyway, im waiting maybe in the future they ll make something available for my sensor too
