twack_32? the toolkit sample twack_32 that you have the source code to?
Not unless you specifically sent a triplet with twack_32, more likely you’re seeing the default behaviour of the device. Many devices retain the capability settings from the last successful acquisition.
But you may be right about their being custom caps on your Canon.
