I am using the project DRD example from the STM32_USB-Host-Device_Lib_V2.1. There are two types of OTG devices: dual-role devices and peripheral-only devices. A dual-role device can function as either a USB peripheral or an OTG host. Dual-role devices must be able to supply at least 8 mA on VBUS. Though a peripheral-only device has no host capabilities, it must be able to request a dual-role device to communicate with it

Although the register values affect the settings of the USB OTG module, the content of the registers does not change during access. In Device mode, this address defines the USB device address as assigned by the host dur- ing the SETUP phase.

The USB OTG defines two roles for devices: OTG A-device and OTG B-device, specifying which side supplies power to the link and which is the host initially. Since every OTG controller supports both roles, they are often called Dual-Role controllers rather than OTG controllers. USB 3.0, on the other hand, can make devices into either hosts or peripherals. Some devices can take either role. The cable turns the Micro-USB port on your mobile device into a USB OTG host port, so that you can connect a Mini-USB drive or other Mini-USB device, such as a game controller, directly to your phone or tablet.

An USB OTG IP Core is ideal for applications where the target device must act as a peripheral and as a host, depending the situation. It provides portable devices with a cost-effective way of conducting point-to-point communications using the USB bus. A good example is a PDA which has to be a peripheral that can sync with a host PC, but can also be a host when a peripheral, such as a keyboard. Most of the new Android devices announced these days come with support for USB OTG. OTG, short for on-the-go, lets you connect USB peripherals like mouse, keyboard, pen drives or other extensible storage devices. Using USB OTG cables, you can be more productive without carrying docks or dedicated accessories. Today, we take a look at some USB OTG cables that support charging while connected The USB host port inside the Pi is an On-The-Go (OTG) host as the application processor powering the Pi, BCM2835, was originally intended to be used in the mobile market: i.e. as the single USB port on a phone for connection to a PC, or to a single device. In essence, the OTG hardware is simpler than the equivalent hardware on a PC The USB host function on recent Android phones and tablets, is perhaps the most unspoken yet incredibly useful innovation in recent mobile device development. I remember, a few years ago some. The USB specification defines a USB transfer as composed of one or several transactions whose size is equal to the maximum endpoint packet size except for the last transaction which can be a short packet or a zero-length packet. In a transfer-based controller, when the µC/USB-Device stack submits a multi-transactions transfer to the controller, this one will automatically split the transfer.
