| // The D+ and D- USB signals should be connected to two pins of the same |
| // I/O port. The following macros define the port letter and the input |
| // bit numbers: |
| #if! defined (__AVR_ATtiny45__) |
| #define USBTINY_PORT C |
| #define USBTINY_DPLUS 1 |
| #define USBTINY_DMINUS 0 |

| // The D+ signal should be connected to an interrupt input to trigger an |
| // interrupt at the start of a packet. When you use the same pin for the |
| // D+ USB signal and the interrupt input, only two I/O pins are needed |
| // for the USB interface. The following macro defines the interrupt |
| // number: |
| #define USBTINY_INT 0 |
| |
| // The power requirement of the USB device in mA, or 0 when the device |
| // is not bus powered: |
| #define USBTINY_MAX_POWER 10 |

| // The USB vendor and device IDs. These values should be unique for |
| // every distinct device. You can get your own vendor ID from the USB |
| // Implementers Forum (www.usb.org) if you have a spare $1500 to kill. |
| // Alternatively, you can buy a small range of device IDs from |
| // www.voti.nl or www.mecanique.co.uk, or be naughty and use something |
| // else, like for instance product ID 0x6666, which is registered as |
| // "Prototype product Vendor ID". |

| // Normally, usb_setup() should write the reply of up to 8 bytes into the |
| // packet buffer, and return the reply length. When this macro is defined |
| // as 1, you have the option of returning 0xff instead. In that case, the |
| // USB driver will call a function usb_in() to obtain the data to send |
| // back to the host. This can be used to generate the data on-the-fly. |
| #define USBTINY_CALLBACK_IN 1 |
| |
| // When this macro is defined as 0, OUT packets are simply ignored. |
| // When defined as 1, the function usb_out() is called for OUT packets. |

| // a control transfer. |
