2.5 Bulk Transfer

A bulk transfer is used to communicate large amounts of data between the USB host and the USB device. Bulk

transfers are supported via bi-directional communication flow, according to the data direction. A bulk OUT transfer is

the data flow from the USB host to the USB device, and a bulk IN transfer is the data flow from the USB device to the

USB host.

Figure 2.13 shows data directions of the bulk IN and bulk OUT transfers.
