I was just playing with my Junebug and having it connect to chips and stuff so when I plugged in my Unicorn into the USB port (it had no programming, just to power it) the LED did not light up (I added a power LED). I then short out the PTC fuse and it powers up. I then de-solder the PTC fuse and take off the plastic cover and look inside at the spring? thing and I see that it is fried! I never powered from the USB before so I am wondering whats up. I replaced it with a ferrite bead.
