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
