4.9
Enumeration
Enumeration refers to the process that begins by the host recognizing the device connected to
the bus, specifying an address, and fixating the descriptor information received from the device.
The USB device uses the descriptor to inform the host of its attributes. There are several types of
descriptors that the host can request. In turn, the device returns information that describes itself
to the host. The USB device is ready to be used by the host when it has been assigned an
address and its configuration has been recognized. (Refer to Figure 6 below)
