for your device
- CONFIG_USBD_PRODUCTID 0xFFFF
+ Some USB device drivers may need to check USB cable attachment.
+ In this case you can enable following config in BoardName.h:
+ CONFIG_USB_CABLE_CHECK
+ This enables function definition:
+ - usb_cable_connected() in include/usb.h
+ Implementation of this function is board-specific.
+
- ULPI Layer Support:
The ULPI (UTMI Low Pin (count) Interface) PHYs are supported via
the generic ULPI layer. The generic layer accesses the ULPI PHY
