• Optionally supports Session Request Protocol
• Can be bus-powered or self-powered
11.24.3
The OTG dual role device supports both USB host and
device functionality. OTG dual role devices use a
micro-AB receptacle. This allows a micro-A or a micro-
B plug to be attached. Both the micro-A and micro-B
plugs have an additional pin, the ID pin, to signify which
plug type was connected. The plug type connected to
the receptacle, micro-A or micro-B, determines the
default role of the OTG device, host or device. An OTG
device will perform the role of a host when a micro-A
plug is detected. When a micro-B plug is detected, the
role of a USB device is performed.
When an OTG device is directly connected to another
OTG device using an OTG cable (micro-A to micro-B),
Host Negotiation Protocol (HNP) can be used to swap
the roles of host and USB device between the two with-
out disconnecting and reconnecting the cable. To differ-
entiate between the two OTG devices, the term “A-
device” refers to the device connected to the micro-A
plug and “B-device” refers to the device connected to
the micro-B plug.
11.24.3.1
In OTG dual role, operating as a host, the following fea-
tures and requirements describe an A-device:
• Supports the devices on the TPL (class support is

• Device drivers are not required to be updateable
• A single micro-AB receptacle is used
• Full-speed protocol must be supported (high-

• Supports at least one form of SRP
• A-device supplies V
11.24.3.2
In OTG dual role, operating as a USB device, the fol-
lowing features and requirements describe a B-Device:

• Draws 8 mA or less before configuration
• Is typically self-powered, due to low-current

11.24.4.1
The USB specification defines full-speed operation as
12 Mb/s and low speed operation as 1.5 Mb/s. A data
line pull-up resistor is used to identify a device as full
speed or low speed. For full-speed operation, the D+
line is pulled up; for low-speed operation, the D- line is
pulled up.
