Linux-2.6.22.6 内核移植--添加USB设备驱动

【实验目的】
 在FS2410开发板上进行linux-2.6.22.6内核的移植，这个部分完成USB设备驱动的添加，完成相应的功能。
【实验环境】
1、Ubuntu10.10发行版
2、FS2410平台以及开发板中移植好的u-boot-1.3.1 
3、交叉编译器 arm-linux-gnu-gcc （ver:3.4.5）
【实验步骤】
(1) 配置2.6.22.6支持u盘
1.
 SCSI device support  --->
<*>   SCSI disk support
      <*>   SCSI generic support
      <*>   SCSI media changer support
       [*] Probe all LUNs on each SCSI device

   这些配置是对host端和device端的支持.
           2. USB support  ---> 
       <*>   USB Mass Storage support
   这是对U盘的SCSI类型的支持
 
 3. File systems  --->
 Native Language Support  --->  (iso8859-1) Default NLS Option
                      <*>   Codepage 437 (United States, Canada)
                      <*>   Simplified Chinese charset (CP936, GB2312)
                      <*>   NLS ISO 8859-1  (Latin 1; Western European Languages)
   支持相应的语言
(2) 启动开发板
插入U盘[靠近SD卡的USB口],出现一下信息：
[root@192 /]# usb 1-1: new full speed USB device using s3c2410-ohci and address2

（3）验证一下
 # mkdir -p /mnt/udisk
 # mount -t vfat -o codepage=936,iocharset=cp936 /dev/sda1 /mnt/udisk
 #cd /mnt/udisk
 # ls
