* \defgroup asfdoc_sam0_usb_group SAM Universal Serial Bus (USB)
*
* The Universal Serial Bus (USB) module complies with the USB 2.1 specification.
*
* The following peripherals are used by this module:
* - USB (Universal Serial Bus)
*
* The following devices can use this module:
* - Atmel | SMART SAM D21
* - Atmel | SMART SAM R21
* - Atmel | SMART SAM D11 (Only USB device support on SAM D11 device)
* - Atmel | SMART SAM L21
* - Atmel | SMART SAM L22 (Only USB device support on SAM L22 device)
* - Atmel | SMART SAM DA1
*
* The USB module covers following mode:
* \if USB_DEVICE_MODE
* - USB Device Mode
* \endif
* \if USB_HOST_MODE
* - USB Host Mode
* \endif
*
* The USB module covers following speed:
* \if USB_HS_MODE
* - USB High Speed (480Mbit/s)
* \endif
* - USB Full Speed (12Mbit/s)
* \if USB_LS_MODE
* - USB Low Speed (1.5Mbit/s)
* \endif
*
* \if USB_LPM_MODE
* The USB module supports Link Power Management (LPM-L1) protocol.
* \endif
*
* USB support needs whole set of enumeration process, to make the device
* recognizable and usable. The USB driver is designed to interface to the
* USB Stack in Atmel Software Framework (ASF).
*
* \if USB_DEVICE_MODE
* \section asfdoc_sam0_usb_device USB Device Mode
* The ASF USB Device Stack has defined the USB Device Driver (UDD) interface,
* to support USB device operations. The USB module device driver complies with
* this interface, so that the USB Device Stack can work based on the
* USB module.
*
* Refer to <a href="http://www.atmel.com/images/doc8360.pdf">
* "ASF - USB Device Stack"</a> for more details.
* \endif
*
* \if USB_HOST_MODE
* \section adfdoc_sam0_usb_host USB Host Mode
* The ASF USB Host Stack has defined the USB Host Driver (UHD) interface,
* to support USB host operations. The USB module host driver complies with
* this interface, so that the USB Host Stack can work based on the USB module.
