So that do I do know?
What you see is an oversight in Exec: Normally, old libraries provide a
main interface with all the previous functionality, named "main". When
calling OpenLibrary, it automatically executes GetInterface(.., "main",
...), since this is used by legacy jump tables.
To prevent this from happening, add the tag item
CLT_NoLegacyIFace, TRUE,
to the CreateLibrary tag list.
I'm not sure, though, if that's already in the released kernel. You
might want to add the tag nontheless (it's not rejected because of
this). If it's not part of your header files, it's defined as
#define CLT_NoLegacyIFace (TAG_USER + 12)
If in doubt, give the interface a meaninngful name. In the case of
libusb, "usb" might be a good idea.
