The configuration is stored in NVRAM on the maXTouch chip. When the device is
reset it reports a CRC of the stored configuration values. Therefore it isn't
necessary to send the configuration on each probe - we can check the CRC
matches and avoid a timeconsuming backup/reset cycle.

Shouldn't this be u32?
It's losing data causing the checksums not to match for me.
