Now if you move the stylus to all the corners, what range of values do

Samuel: When I move the stylus on the right-hand side of the tablet no
ABS-X coordinate is reported; only ABS-Y keeps changing. This may be
the problem, but I do not know how to solve it.

What is the maximum value it gets to? Also, do you mean that there's only an ABS-Y in the packet? It sounds like either the tablet isn't reporting correctly or the kernel hid driver is interpreting it incorrectly. Are there any relevant messages in the journal.

Something I just discovered is an application called "hidviz". It directly talks to the device over the HID interface and shows what it finds. Try running it and select the interface for the stylus. Copy the output from the Descriptor View and then watch the values in the Device View as you move the stylus around, particularly in the right side.
