Check if USB power is present.
Devices which don't support checking the USB power state must always return true.
Implements USBPhy.
|
virtual |
Make the USB phy visible to the USB host.
Enable either the D+ or D- pullup so the host can detect the presence of this device.
Implements USBPhy.
|
virtual |
Detach the USB phy.
Disable the D+ and D- pullup and stop responding to USB traffic.
Implements USBPhy.
|
virtual |
Set this device to the configured state.
Enable added endpoints if they are not enabled already.
Implements USBPhy.

virtual |
Get the endpoint table.
This function returns a table which describes the endpoints can be used, the functionality of those endpoints and the resource cost.
Implements USBPhy.
|
virtual |

Callback used for performing USB processing.
USBPhy processing should be triggered by calling USBPhyEvents::start_process and done inside process. All USBPhyEvents callbacks aside from USBPhyEvents::start_process must be called in the context of process
