Continued from the above: Teach you step by step how to use USB CDC + MSC composite device (based on stm32f407)
This article mainly records some data captured during usb enumeration and some scsi protocols involved in usb msc.
USB MSC Protocol
Mainly include usb protocol, msc protocol, scsi protocol, and SDIO interface protocol. The flow chart is as follows, describing the communication process between Host and Dev.
SCSI Protocol
SCSI: Small Computer System Interface, the abbreviation of small computer system interface. In human terms, it means that the Host communicates with the device through the USB protocol, and the data in the USB protocol uses SCSI protocol is used to transmit SD card or hard disk data to achieve the function of mounting the SD card on the computer and reading and writing files.
Several commonly used SCSI protocols are as follows:
| Command code | Description | Meaning |
|---|---|---|
| 0x00 | SCSI_TEST_UNIT_READY | Test command, frequently used |
| 0x12 | SCSI_INQUIRY | Query basic information commands, including Manufacturer, version and other information |
| 0x1a | SCSI_MODE_SENSE6 | Mode Detection, providing a series of device services, report parameters, etc. |
| 0x15 | SCSI_MODE_SELECT6 | Mode selection, corresponding to 0x1a |
| 0x23 | SCSI_READ_FORMAT_CAPACITIES | Read supported formatted capacity |
| 0x25 | SCSI_READ_CAPACITY10 | Read current SD card capacity |
| 0x28 | SCSI_READ10 | Read data command |
| 0x2f | SCSI_WRITE10 | Write data capacity |
| … | … | … |
Enumeration process data
The following is the data captured by BusHound during the enumeration process.
Bus Hound 6.00 capture on Windows Vista (x64). Complements of www.perisoft.net
stm32 normal process
Device - Device ID (followed by the endpoint for USB devices)
(6) USB Root Hub (USB 3.0)
(26) USB Mass Storage Device
(27) STM Product [ROM=0.01]
Address - FireWire async address or channel number
Length - Total transfer length
Phase - Phase Type
ATA ATA task file command SENSE SCSI sense data
CTL USB control transfer USTS USB status
IN Data in transfer ok command complete
OUT Data out transfer
Data - Hex dump of the data transferred
Descr - Description of the phase
Cmd... - Position in the captured data
