* Don't assume 0x41 messages only occur when a device is first paired
(prevents errors when waking from sleep or turning a device on)
* Delay reads/writes when a device is powered on, to prevent broken pipe
errors (hacky solution).
* Don't clear status when a device connects, preventing settings from being
cleared when a device sleeps or is turned off.
* Fix typos.
