So, there are at least two problems here.

The most significant is that the F-0590B is not the same thing as the
Quickcall device which quickcalld supports[1], so there's really no
way it's going to work.

In any case quickcalld needs to take the path under sysfs to the
specific device, not just "/sys".  That path is most easily supplied
by the included udev rules file.
