Change PORT

Post by pcboy » Sat Jan 06, 2007 3:16 pm

I have some problem with your AVR USB driver on an AVRMEGA64 MCU.
The problem is, when I Change default USB bus (PORTB PB0,PB1) to
any other Ports like PORTC in "usbconfig.h" the device will not be recognised by Windows.
I do a "clean" and "Rebuild all" but it dosent work , please tell me what i do ?

Please see the thread "usb driver problem". You probably have not set the I/O ports used for USB as inputs without pull-up or other parts of your firmware still output data to these pins.
