Major USB update, fixes most (if not all) known issues USB - General - Refactored descriptors - Enabled/Disable USB endpoints - Added debug flags for special features - Code cleanup - Interface count calculation based off of enabled endpoints - Delayed wTotalLength calculation to simplify descriptor offsets - Re-ordered endpoints and interfaces - Added more debug output - Added usbInitTime to show how long keyboard initialization took (Useful when debugging bad init sequences) - Added function for usb_resume() which takes care of the resume sequence * Resume is now only called if packets are starting to timeout USB - Special Options - Added enableDeviceRestartOnUSBTimeout * A last resort hammer for bad USB Chipsets/OSs, don't use if you can help it * Disabled - Added enableUSBResume * Enables host resume wake-up signalling, required to wake a computer from sleep * Enabled - Added enableUSBLowPowerNegotiation * Enables power negotiation hack * Required to use firmware with an IPad and other hard-limit low-power USB hosts * Hasn't been tested with the recent changes * Disabled - Added enableUSBSuspend * Enables power down events on host USB bus suspend * Enabled USB - Keyboard - Attempted to cleanup HID SET_REPORT * Works much better * Still has an issue under Linux which generates *a lot* of NAKs (initializes quickly regardless) + Not present on other keyboards + SETUP -> OUT -> IN : This sequence is the problem + Specifically during the OUT phase - Enabled USB - CDC Virtual Serial Port - Code cleanup - Added convenience struct USBCDCLineCoding for easier debugging - Attempted to cleanup CDC_SET_LING_CODING * Works much better * Still has an issue under Linux which generates *a lot* of NAKs (initializes quickly regardless) + SETUP -> OUT -> IN : This sequence is the problem + Specifically during the OUT phase + Likely the same issues as HID SET_REPORT - Enabled USB - Mouse - Enabled USB - Joystick - Disabled USB - RawIO - Initial code, API not used yet - Disabled DFU - Updated load script, now faster
