How Linux configuration identifies a USB flash drive

1. Configuration required in kernel

2. Device Drivers (USB drive belongs to storage device, Linux defines it as SCSI device)
4. SCSI Device Support--->
6.     <*> scsi device support                                                                                           
8.     <*>   scsi disk support                                                            
10.     usb support  --->  
12.     <*> support for  host-side usb                                                            
14.             [*]    USB device filesystem                                                             
16.             ---    USB Host Controller Drivers                                                       
18.             <*>    EHCI HCD  (Usb 2.0
20.             <*>    OHCI HCD support                                                                 
22.             <*>    UHCI HCD  (most intel and  via)  support                                            
24. <*> USB Mass Storage Support
26. File systems>
28. DOS/FAT/NT filesystems---> (USB stick is usually in the format under Windows)
30. <*> MSDOS FS Support
32.         <*> vfat  (Windows-< Span class= "number" style= "margin:0px; padding:0px; Border:none; Background-color:inherit ">95
34. <*> NTFS File system support PCOP

2. <*>ntfs Write support
4. native language support  --->  
6. <*>   codepage 437   (united states,  Canada)   
7. <*> NLS ISO 8859-1 (Latin 1; Western European Languages)

   2. Mount various formats of USB flash drive, command:

   Mount/dev/sda/mnt/usb Some systems need to specify the type of file system, you can use Mount-t Vfat/dev/sda/mnt/usb

   Mount the USB device to the/MNT/USB directory: The file system is fat32mount-t Vfat/dev/sda1/mnt/udisk or if it is a different file format, such as Fat12mount-t msdos/dev/sda1/mnt/ Udisk to correctly display the possible Chinese fonts, set the input and output character type to cp936. Mount-t Vfat-o Iocharset=cp936/dev/sda1/mnt/udisk

   
   

9. 3. Query whether there is a USB stick identification, you can use the following command:
   Generally plug in a USB stick, if identified:
   # tail-f/var/log/messages  //There will be some log of the USB register.
   # Fdisk-l//can view the drive letter that can be formatted
   # Mount //See if a USB flash drive is available on the mount, command view
