To achieve that communication, USB connected devices use file system protocols. Embedded devices connected through USB have two different ways of revealing the stored contents of their media: USB Mass Storage (UMS), and the Media Transfer Protocol (MTP).
What is USB packet format?
There are 4 main USB packet types :Token, Data, Handshake and Start of Frame. Each packet is constructed from different field types, namely SYNC, PID, Address, Data, Endpoint, CRC and EOP. The packets are then bundled into frames to create a USB message.11 nov. 2009
What format is USB data transfer?
Most USB flash drives will have a FAT32 file system out of the box. It is the most compatible file system for older/modern computers (PC and Mac), plus gaming consoles and other devices with a USB port. exFAT is the ideal file system for USB flash drives.
Is USB packet based?
During USB communication, data is transmitted as packets. Initially, all packets are sent from the host via the root hub, and possibly more hubs, to devices. Some of those packets direct a device to send some packets in reply.
