# UsbEndpoint

<br />

*** ** * ** ***

A class representing an endpoint on a `https://developer.android.com/reference/android/hardware/usb/UsbInterface`. Endpoints are the channels for sending and receiving data over USB. Typically bulk endpoints are used for sending non-trivial amounts of data. Interrupt endpoints are used for sending small amounts of data, typically events, separately from the main data streams. The endpoint zero is a special endpoint for control messages sent from the host to device. Isochronous endpoints are currently unsupported.

## Summary

### Inherited constants

From interface `https://developer.android.com/reference/android/os/Parcelable` `int` `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR`

Descriptor bit used with `https://developer.android.com/reference/android/os/Parcelable#describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.
