Supported Arduinos (IDE 1.6.6 or higher!):

• Uno (with HoodLoader2)
• Mega (with HoodLoader2)
• Leonardo
• (Pro)Micro
• Any other 8u2/16u2/at90usb8/162/32u2/32u4 compatible board

Supported HID devices:

• Keyboard with Leds out (modifiers + 6 keys pressed at the same time)
• NKRO Keyboard with Leds out (press up to 113 keys at the same time)
• Mouse (5 buttons, move, wheel)
• Absolute Mouse
• Consumer/Media Keys (4 keys for music player, web browser and more)
• System Key (for PC standby/shutdown)
• Gamepad (32 buttons, 4 16bit axis, 2 8bit axis, 2 D-Pads)

####Some experiments showed that:

• Make sure to not use too many HID devices at once. This can cause trouble with some OS.
• Changing the devices causes driver problems under Windows
• Mouse + Keyboard + System + Consumer works fine
• Mouse and Absolute Mouse together dont work fine
• Mouse Abs only works with system report under special circumstances.
• Mouse and Gamepad together causes problems
• Using Gamepad with any other HID device causes trouble
• All OS have some problems with Gamepads. Dont use more than one device for Linux and be careful when you change the descriptor.
• RawHID is not working properly, test it at your own risk.
• XBMC 13.1 (a Media Center, now Kodi) uses Gamepad input. Its seems to not work and may cause weird errors. Even with a standard Gamepad I have these errors. Just want to mention it here.
