See issue #9.
Some people have asked me about Midi support. It is not planned to integrate Midi into the HID-Project USB-Core since it is very complicated to do so. But I will work on a new Midi firmware for the 16u2 that supports of course Midi (HoodLoader2 only). A firmware is something like a pre-compiled sketch. With the difference that I wont use the Arduino IDE to create this firmware. I will use Lufa and a makefile to compile this firmware. This is more efficient.
When the firmware is done you may upload it via avr-dude as described on the HoodLoader2 github page. Then you are able to start the midi with a simple reset or start the bootloader (HoodLoader2) again with a double reset like you are used to. Then you can reprogram your 328 again.
So be patient, I have a lot of new stuff planned and Midi will come. But you are able to flash other firmwares like HIDuino. Maybe thats all you need. Install HoodLoader2 and flash the hex file. If it works please leave me some info.

is mostly solved by a pc reboot or a port switching. Try another (USB2.0) port if you have any problems with your device. You might also try it on another pc to see if your OS mixes up drivers. Once I had a problem with my USB-Hub, so ensure to connect it directly. You could also try a different/shorter USB cable.
might confuse the OS since the USB device changes completely from one second to the other. Therefore go to Printers and Devices on Windows and select remove. Reconnect your Arduino and maybe remove it again if its not working properly. Alternatively you can also restart your PC or use another USB PID (in the boards.txt) to see if its a Windows problem or not. If you change the USB PID the CDC Driver wont be loaded but you can always reupload a sketch in bootloader mode.
This happened to me on a specific windows installation after each reboot. Go to 'This Pc -> Manage -> Device Manager -> Other devices -> HoodLoader2', right click and hit 'Update Driver Software... -> Search automatically [...]'.
had several problems over the time. The first thing I'd like to mention is that the calibration windows only updates if you focus it. Windows only supports gamepads with up to 7 axis and 32 buttons and has problems with more than one Gamepad in a multireport. Linux has problems when gamepads are in multi reports with a system device for example. It may occur that it display immense axis/buttons or none at all. The current gamepad setting was tested under windows and ubuntu and seems to work. Feel free to extend the gamepad report at your own risk.
If you have any other problem, open an issue on github or contact me on my blog.
