# USB live connection
There are times when it works correctly and times when it doesn't.
It works more stably if you connect before starting the firmware.
When it works correctly, a log like this will be displayed.
```
I (796) usb_hid: hid_host_device_callback
I (796) usb_hid: HID Device, protocol 'KEYBOARD' CONNECTED
I (806) usb_hid: hid_host_device_callback
I (806) usb_events: event_flags=0x0
I (816) usb_hid: HID Device, protocol 'NONE' CONNECTED
I (816) usb_events: event_flags=0x0
