?安裝、以root身份登錄linux,

1.檢查核心是否加載USB模塊
# dmesg | grep usb

有輸出如"usb.c: registered....."信息說明模塊已加載,否則需要執行:

# modprobe usb-uhci
# modprobe usb-storage

# dmesg |grep usb
....
....
registered new drver usbdevfs

2.連接好USB硬盤,

# dmesg tail

....
....
hub.c: USB new device connect on bus1/2, assigned device number 3
usb-uhci.c: interrupt, status 3, frame# 1489

發現USB設備,對應的設備為 /dev/sda1

# mkdir /mnt/usbdisk
# mount -t vfat /dev/sda1 /mnt/usbdisk

這樣您就可以通過usbdisk目錄訪問usb的文件了.

-t vfat 只能mount fat文件系統..
對于ntfs的文件系統mount就稍復雜一點了.
