Enhanced the USB MSC host example to support multiple simultaneously
connected Mass Storage Class (MSC) devices.
- Implemented dynamic allocation and mounting of multiple MSC devices.
- Improved example logic for handling USB device connections and disconnections.
- Updated documentation to clarify USB host limitations and endpoint allocation.
This commit updates the USB Host stack to use the USB PHY driver. The
USB PHY and the OTG Controller should now both be setup/deleted using
usb_new_phy() and usb_del_phy() respectively.
- The hcd_install() now expects the USB PHY and OTG Contorller to be
already setup before it is called
- usb_host_install() now has an option to skip calling usb_del_phy() if
the user wants to setup their own USB PHY (e.g., in the case of using
and external PHY).
- CDC-ACM and MSC examples/test updated to use internal PHY
