Linux下命令行支持USB设备

将USB设备插上电脑，流程如下

[root@vmserver admin]$ su
[root@vmserver admin]# mkdir /mnt/usb
[root@vmserver admin]# dmesg | tail

Attached scsi generic sg4 at scsi5, channel 0, id 0, lun 0,  type 0
USB Mass Storage device found at 6
root@vmserver admin]# mount -t vfat /dev/sdb1 /mnt/usb

注意第8行，最终的设备名称是sdb1而不是sdb,使用的文件系统类型为vfat。
