ls 120 usb drive

For the entire USB-storage module, the usb_stor_init () function is its start. However, for the USB flash drive, the function that actually drives the USB flash drive starts with the storage_probe () function. As long as the two parallel lines overlap, it is doomed to start

But the code in this directory does not live in a paradise. They are always closely related to the outside world. You can continue to see: Lfg1:/usr/src/linux-2.6.22/driv

. To this end, the program must be modified. One idea is to open a thread and run the Recv. It doesn't matter if you stop it. The other idea is to change the sock to non-blocking. For details about the changes, see. red lines in the H file! Int flags = fcntl (hotplug_sock, f_getfl, 0 );Fcntl (hotplug_sock, f_setfl, flags | o_nonblock ); When the kernel has no message, the Buf after Recv () is empty. After cross-compilation, the program runs well in tiny210! Previous: Unfortunately, the industry

After making the partition, use the maintenance USB flash drive to start WinPE and run DiskGenius to partition the mobile hard disk. If the hard disk is a common hard disk, partition it as needed, 4 K alignment is required for solid state disks, as shown in figure: (some people

The file system read-only problem occurs on the USB flash drive under Ubuntu. The problem is that existing files in the USB flash drive cannot be deleted and new files cannot be copied to the USB flash drive. But I don't know why.
