I bought an Arduino pro micro (looks like this) from a Chinese seller over E-Bay, for its HID interface.

I installed the Arduino software on my Linux machine (Kali Linux), and started writing a USB Rubber Ducky script, and converted it to Arduino using Dckuino.js, which usually works just fine.

I may have used either:

  • The wrong programmer, or
  • The wrong board type

because when I uploaded the sketch, it said it failed, but HID script still worked when I plugged it into my Mac.

The Mac came up with a Keyboard Assistant, because it couldn't recognize the keyboard being use. So I plugged it back into my Linux machine, and it wouldn't recognize.

  • lsusb and dmesg -w didn't show any updates when re-plugging the Arduino.
  • Changing USB chords didn't work.
  • Switching over to windows, Device Manager didn't do the normal "refresh" when you plug in a new device, and there was nothing under COM Ports.
  • The HID input didn't work on the Mac anymore, when plugging it in again.
  • The inbuilt LED lights up when connected.

Is this a brick? I can't seem to find any reset button or header on the board, so I cant connect the ground and reset. There is an RST header, but I don't know what that is.

Any help would be greatly appreciated!

    RST = ReSeT. Have you tried re-flashing the bootloader through ICSP? – Majenko May 3 '18 at 10:59

  • Connecting the RST header to ground (GND) with a wire should be the same as pressing the reset button on other arduinos. – Craig May 3 '18 at 14:53
  • Do I need to solder on the wire, or can I just kind of hold it there? – Jacob Collins May 3 '18 at 21:30
  • Don't play with RST. Get another arduino. Load programmer sketch. And try to load bootloader over icsp. Select programmer "arduino as isp" – Mert Gülsoy May 6 '18 at 22:10
