My version is also 2.1, and now you want to load the U disk, then have to manually mount (mount-t vfat / dev / block / sda / usb /) down to see the contents of the U in / usb / where is it because / system / core / vold / vold.c Lane ums_bootstrap function is empty ah? If the reference mmc_bootstrap perfect ums_bootstrap, then, is not allowed to do so?

In addition, I found insert U disk will add a file: / sys/class/usb_device/usbdev1.1x, x is the number of times as you insert and change,

Landlord, is running on a real machine do? I now realize automatically mount U disk, data say a lot worse to modify void.fstab file, the file is read-only, then you need to run the mount command, but the command is executed, the system ect I fell void . fstab file guide, and then re-import into the modified, you can still say that the file is read-only system. Very anxious. . . I hope to help the landlord under busy. . . Thank you very much. . .
