With both versions, the rest of the struct is an array containing 0x81-byte (0x21-byte with version <=0x2) entries. With version pre-0x7 there's 4 entries allocated, starting with version 0x7 there's 8 entries allocated. This contains the ExplainText string which includes the NUL-terminator. Each entry corresponds to a controller NpadId, starting with NpadId/controller 0.

Regardless of version, the default data for this struct is setup by setting u32 +0 to 0x01010400, u8 +4 to 0x1, with the rest being cleared as needed. sdknso itself only calls the func for this from ShowControllerStrapGuide, since that's the only time sdknso itself writes to ControllerSupportArg besides ExplainText (and is also the only case where the ControllerSupportArg is not user-specified).
