# OTG
|
||
|
|
|
||
|
|
By default, _scrcpy_ injects input events at the Android API level. As an
|
||
|
|
alternative, when connected over USB, it is possible to send HID events, so that
|
||
|
|
scrcpy behaves as if it was a physical keyboard and/or mouse connected to the
|
||
|
|
Android device.
|
||
|
|
|
||
|
|
A special mode allows to control the device without mirroring, using AOA
|
||
|
|
[keyboard](keyboard.md#aoa) and [mouse](mouse.md#aoa). Therefore, it is possible
|
||
|
|
to run _scrcpy_ with only physical keyboard and mouse simulation (HID), as if
|
||
|
|
the computer keyboard and mouse were plugged directly to the device via an OTG
|
||
|
|
cable.
|
||
|
|
|
||
|
|
In this mode, `adb` (USB debugging) is not necessary, and mirroring is disabled.
|
||
|
|
|
||
|
|
This is similar to `--keyboard=aoa --mouse=aoa`, but without mirroring.
|
||
|
|
|
||
|
|
To enable OTG mode:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
scrcpy --otg
|
||
|
|
# Pass the serial if several USB devices are available
|
||
|
|
scrcpy --otg -s 0123456789abcdef
|
||
|
|
```
|
||
|
|
|
||
|
|
It is possible to disable HID keyboard or HID mouse:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
scrcpy --otg --keyboard=disabled
|
||
|
|
scrcpy --otg --mouse=disabled
|
||
|
|
```
|
||
|
|
|
||
|
|
It only works if the device is connected over USB.
