I was trying to figure out why I couldn’t connect and I discovered that the USB cable was hot.
So, in addition to burning, it also shorted out, which turned my USB cable into a heater. I checked and it can pull +5A without activating any fuses. I think it would be good to review this.
I disassembled it and discovered that it was the processor that burned. Since it looks like a memory stick, I disconnected it, and then when I turned it on, the red LEDs lit up in a scanning pattern.
