hub. At the beginning of the connection, the device is always assigned to address "0". Thereafter,
the host assigns an address from 1 to 127. Each function and hub has several buffers for
transferring data over the USB called endpoints. A full speed device can have up to 16 endpoints,
while a low speed device can have up to three. Each endpoint is defined with an endpoint
number, transfer direction, transfer method, and maximum packet size. Each definition uses a
specific endpoint. All USB devices must have endpoint 0 to support control transfers.
The host communicates by specifying addresses and endpoint numbers that it assigns to each
When the USB device is connected, the host assigns a unique address to each function and
