1. Control transfer must use endpoints with one bank and can be aborted using a stall handshake.
2. Isochronous transfers must use endpoints configured with two or three banks.

Isochronous OUT Transfer
A transfer is composed of one or several transactions;
An endpoint handles all transactions related to the type of transfer for which it has been
configured.
Each transfer results in one or more transactions over the USB bus.
There are five kinds of transactions flowing across the bus in packets:
Unidirectional
