Endpoint configuration
----------------------
0 Control endpoint
1 keyboard
2 mouse
3 debug
4 extra key(consumer/system)
5 nkro keyboard(supported only on ATmega32U4/16U4 and AT90USB64/128)
ATmega32U4/16U4, AT90USB64/128
• Endpoint 0:programmable size FIFO up to 64 bytes, default control endpoint
• Endpoints 1 programmable size FIFO up to 256 bytes in ping-pong mode.
• Endpoints 2 to 6: programmable size FIFO up to 64 bytes in ping-pong mode.
AT90USB82/162, ATmega8U2/16U2/32U2
• Endpoint 0:programmable size FIFO up to 64 bytes, default control endpoint
• Endpoints 1 and 2: programmable size FIFO up to 64 bytes.
• Endpoints 3 and 4: programmable size FIFO up to 64 bytes with ping-pong mode.
ping-pong mode means double buffer feature.
NOTE: ATmega8U2/16U2/32U2 is not supported with PJRC stack at this time.
TODO: Macro definition for ATmega8U2/16U2/32U2 in usb.h
