TAG

const char* TAG = "USB_MSC"

static

TinyUSB Mass Storage (MSC) class callbacks for the single vfat LUN.

The block device is provided at runtime by a backend (see usb_msc.h) so this file carries no storage dependency. All callbacks target LUN 0; reads/writes are bounds-checked inside the backend.
