The NAND chips cannot talk to your computer on their own. They need a translator—a microcontroller that bridges the gap between the raw memory and the USB port. This controller is usually made by manufacturers like Phison, SMI (Silicon Motion), Alcor, or Chipsbank. The correct approach depends on your operating system
In these cases, the NAND flash is exposed directly to the host PC, bypassing the wear-leveling and bad-block management typically handled by a USB drive's controller. This can cause issues because standard file systems like FAT32 are not designed for raw NAND flash. The solution is to create a backing file on a flash-friendly file system (like JFFS2 or UBIFS) and then use that file as the backing store for the g_mass_storage driver. This is a standard practice in embedded Linux development for creating data logging devices or USB gadgets.
