public class UsbConfiguration extends Object implements Parcelable
UsbDevice
.
A USB configuration can have one or more interfaces, each one providing a different
piece of functionality, separate from the other interfaces.
An interface will have one or more UsbEndpoint
s, which are the
channels by which the host transfers data with the device.
For more information about communicating with USB hardware, read the USB developer guide.

public String toString()
Object
toString
method returns a string that
"textually represents" this object. The result should
be a concise but informative representation that is easy for a
person to read.
It is recommended that all subclasses override this method.
The toString
method for class Object
returns a string consisting of the name of the class of which the
object is an instance, the at-sign character `@
', and
the unsigned hexadecimal representation of the hash code of the
object. In other words, this method returns a string equal to the
value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
