I have an Arduino Nano Every device that seems to have shorted out.
I use a lighted USB hub with buttons that turn connections on and off. Each button has its own LED that indicates power state for its associated port.
Anyway, when I plug my Arduino Nano Every into that USB hub, the lighted buttons turn off for half of the hub, like the Arduino is shorting out the hub.
I use a different Arduino and have no problems, so it's definitely the Arduino.
Any idea what could have caused this? I was using the Arduino with a TMUX1511 switch chip and using pins D9-D12 to turn on and off the 4 internal switches in the chip. It's using very low voltage (5v) and amperage is (25 mA). I used the 5v and gnd pins on the Arduino to power the TMUX1511 chip, but with such low amperage, I can't see how that could have caused the Arduino to fry.
