i am having a hello world problem.
i have an arduino mini 04 and a mini usb adapter wired exactly as the example on the arduino site.
when i plug the usb into my macbook pro, the computer says it's drawing too much power and shuts down the usb port.
i tried using a usb hub with an external power source but still it was not recognized by the computer (possibly the wrong kind of hub?)
yesterday the computer wasn't shutting off the port, but when i tried to upload a program i got the "programmer is not responding" error.
i tried powering the mini from an external 5v as well, which didn't change anything.
has anyone seen this?
