Unable to use AVRISP MKII to burn bootloader

Bump

What is the solution to this!
I've got a custom mega1280 compatible board and want to program with the arduino IDE and a AVRISP mkII

Its all well and good to install AVR Studio, but what the hell is the issue with the arduino IDE?

most the jungo driver be installed?

is the lib usb driver the one here:
..\arduino-0021\hardware\tools\avr\utils\libusb\bin

is there an OS compatibility issue?

i get this message no matter what i try...
avrdude: usbdev_open(): did not find any USB device "usb"
