Hi,
I am trying to use enum's,
but both HIDP_REPORT_TYPE and USAGE cause runtime error (compiles
OK) "Unsupported argument type".
HIDP_REPORT_TYPE is defined in HIDLibrary.java and USAGE is in
USAGE.JAVA .
HIDLibrary.java and USAGE.JAVA are attached.
Unsupported argument type hid.HIDLibrary$HIDP_REPORT_TYPE at
parameter 0 of function HidP_GetUsageValue
Native-side these are integer values. Java-side, they are enum
objects. You have to tell JNA how to translate to the native value,
either with a TypeMapper or by making the enum objects implement
NativeMapped.
