at any time they are powered, regardless if they have been assigned a non-default address, are configured,
or neither. Bus activity may cease due to the host entering a suspend mode of its own. In addition, a USB
device shall also enter the suspended state when the hub port it is attached to is disabled.
The USB controller exits suspend mode when there is bus activity. It may also request the host to exit
suspend mode or selective suspend by using electrical signaling to indicate remote wake-up. The ability
of a device to signal remote wake-up is optional. The USB controller is capable of remote wake-up
signaling. When the USB controller is reset, remote wake-up signaling must be disabled.
32.8.3.1.2
The USB controller moves into the suspend state when suspend signaling is detected or activity is missing
on the upstream port for more than a specific period. After the device controller enters the suspend state,
DCD is notified by an interrupt (assuming DC suspend interrupt is enabled). When the DCSuspend bit in
the USB_PORTSCn is set to a 1, the device controller is suspended.
DCD response when the device controller is suspended is application specific and may involve switching
to low-power operation.
Find information on the bus power limits in suspend state in USB 2.0 specification.
32.8.3.1.3
If the USB controller is suspended, its operation is resumed when any non-idle signaling is received on its
upstream facing port. In addition, the USB controller can signal the system to resume operation by forcing
resume signaling to the upstream port. Resume signaling is sent upstream by writing a '1' to the Resume
bit in the in the USB_PORTSCn while the device is in suspend state. Sending resume signal to an upstream
port should cause the host to issue resume signaling and bring the suspended bus segment (one more
devices) back to the active condition.
32.8.4
The USB 2.0 specification defines an endpoint, also called a device endpoint or an address endpoint as a
uniquely addressable portion of a USB device that can source or sink data in a communications channel
between the host and the device. The endpoint address is specified by the combination of the endpoint
number and the endpoint direction.
The channel between the host and an endpoint at a specific device represents a data pipe. Endpoint 0 for a
device is always a control type data channel used for device discovery and enumeration. Other types of
endpoints supported by USB include bulk, interrupt, and isochronous. Each endpoint type has specific
behavior related to packet response and error handling. More detail on endpoint operation can be found in
the USB 2.0 specification.

Resume
Before resume signaling can be used, the host must enable it by using the set
feature command defined in device framework (chapter 9) of the USB 2.0
specification.
