usbdev_open(): did not find any USB dev on Mac

I'm trying to burn optiboot using an JTAGICE mkII programmer. On Windows I don't have arduino software installed, on Mac I get this error:

usbdev_open(): did not find any USB dev

Where can I modify the avrdude settings for Arduino so I can point it to tty.usbserial-A800ep7B instead of usb (as stated by Arduino [0018]) usbdev_open(): did not find any USB device
