It configures AVR-USB for an ATMega8 with USB D+ connected to Port Dbit 2 (which is also hardware interrupt 0) and USB D- to Port D bit 0. You maywire the lines to any other port, as long as D- is on bit 0 and D+ is alsowired to INT0.To create your own usbconfig.h file, copy this file to the directorycontaining "usbdrv" (that is your project firmware source directory) andrename it to "usbconfig.h". Then edit it accordingly.*//* ---------------------------- Hardware Config ---------------------------- */#define USB_CFG_IOPORTNAME      B/* This is the port where the USB bus is connected. When you configure it to * "B", the registers PORTB, PINB and DDRB will be used. */#define USB_CFG_DMINUS_BIT      0/* This is the bit number in USB_CFG_IOPORT where the USB D- line is connected. * This may be any bit in the port. */#define USB_CFG_DPLUS_BIT       2/* This is the bit number in USB_CFG_IOPORT where the USB D+ line is connected. * This may be any bit in the port.

We have introduced this configuration * option to allow you to change the data segment where this buffer is * allocated. If you have problems with the default segment (start of .bss), * you may change this setting. See the comment in usbdrv.h for details. * On IAR C, the default is the TINY_Z segment (first 256 bytes). You must * change this default for devices which don't have RAM below 0x100. *//* --------------------------- Functional Range ---------------------------- */#define USB_CFG_HAVE_INTRIN_ENDPOINT    1/* Define this to 1 if you want to compile a version with two endpoints: The * default control endpoint 0 and an interrupt-in endpoint 1. */#define USB_CFG_HAVE_INTRIN_ENDPOINT3   1/* Define this and USB_CFG_HAVE_INTRIN_ENDPOINT to 1 if you want to compile a * version with three endpoints: The default control endpoint 0, an * interrupt-in endpoint 1 and an interrupt-in endpoint 3. */#define USB_CFG_IMPLEMENT_HALT          0/* Define this to 1 if you also want to implement the ENDPOINT_HALT feature * for endpoint 1 (interrupt endpoint).
