- Somewhat aggresive, may cause restarts if the keyboard/OS hasn't fully intialized the keyboard - Added GET_IDLE handling and correct usage of SET_IDLE - Initial implementation of idle send, commented out as it causes issues on Mac OSX for sleeping (keyboard has been working without it) - MacOSX seems to have some sort of data corruption on the USB link, not sure why (other OSs have no issues) - Cleaned up some code - Added a longer sleep after the resume sequence to prevent possible issues sending keys too soon (may need to be increased more) Ipad support now seems flaky, though Mac, Windows seems solid. Init sequence on Linux seems slow, even though there are no errors.blockKey
