bootloader error

Hi, I am trying to load the bootloader to an Arduino Mega1280 using an atmel AVRISP mkII with Arduino0017/0018. I get the error message: Using Port : usb Using Programmer : stk500v2 avrdude: usbdev_open(): did not find any USB device "usb" Any ideas what I am doing wrong? Jim

It sounds like you either haven't selected the right serial port from the tools menu or the PC is not recognising the USB bridge. Have you loaded the drivers? Can you see the port in the other applications?

In Tools – Serial Port only one port shows up and that is the Arduino Mega. I can upload sketches to the Arduino. Also using the AVR Studio 4 that came with the programmer I can read the fuses, power and some other stuff from the Arduino.
