hi,
i have a program for connecting atmega8 with usb, and send data from avr to PC.
but when i debug the code with avr studio, these errors appear" undefined reference to `usbPoll, undefined reference to `usbMsgPtr', undefined reference to `usbInit'".
and when i include "usbdrv.c" in main function this is the error "undefined reference to `usbCrc16'"
this variable is in "usbdrv.c"
i am beginner, could someone help me please?
