Hello, I have a little problem (maybe very stupid, by I'm novice in USB stuff)

As I understand, to config the pins on port D (for D+ and D-) it's neccesary to define these lines

#define USB_CFG_DMINUS_BIT 0
#define USB_CFG_DPLUS_BIT 2

But if I define DMINUS_BIT with bit 4 or other (and connect pin to USB circuit) Windows can't find the device. It works ONLY with DMINUS_BIT = 0. But I want to free the USART pin.

Orig. schematic I use:

Did you do a "make clean" after the change? Most of the makefiles don't have dependencies on usbconfig.h and don't recompile after a change.

Other than that: Are you sure the wiring is OK?

yep, I did "clean all". I solved the problem shifted D+ & D- to the port B bit0 and bit1 and connected D+ line to the Pd2/Int0 pin (Atmega8)

In this config it works )
