# systemd USB monitor example

Simple example about systemd (sd-event & sd-device) to monitor USB devices on connection

## Compile and Run

Compile with **gcc**:

```

gcc usb_sd_device_monitor.c -o usbthingy `pkg-config --libs --cflags libsystemd`

```

And run it:

`./usbthingy`

**Note:** It's quite possible that on **Ubuntu** you'll need to install the `libsystem-dev` package. At least was my case for **Ubuntu 23.04** (lunar)

`sudo apt install libsystemd-dev` 

Seems that on **Arch Linux** is already installed.

### Example of output

This is the output that I get when I connect my Zowie mouse:

```bash

syspath: /sys/devices/pci0000:00/0000:00:14.0/usb2/2-1/2-1.3

devtype: usb_device

subsystem: usb

first_sysattr: idProduct

first_tag: seat

id_vendor: 1af3

id_product: 0001

product: ZOWIE Gaming mouse

```
