| USB device controller driver |
| ############################ |
| |
| The USB Device Controller Driver Layer implements the low level control routines |
| to deal directly with the hardware. All device controller drivers should |
| implement the APIs described in :zephyr_file:`include/drivers/usb/usb_dc.h`. |
| This allows the integration of new USB device controllers to be done without |
| changing the upper layers. |
| With this API it is not possible to support more than one controller |
| instance at runtime. |
