I just got the unit and wired it up. It seemed to work fine, and I uploaded the example bink program easily. I changed the blink rate from 1/second to 10/second and hit upload. It looked like it worked, but the unit just stopped responding. when I unplugged it and plugged it back in, it enumerates as a CDC, but when I click on the reset button, it just locks up and does nothing. It worked a couple times then just stopped. I undersand the bootloader is on a separate chip, so i'm not sure how I broke this one. Is there some way to reflash it without the bootloader or is there some way to restore (or test) the bootloader?
