一、代碼修改
在這里把include前面的#給刪了，希望有幫助
/*add by lfc*/
＃include
＃include
＃include
＃include
/*end add*/?

/**********************add by lfc*************************************/
static struct s3c2410_hcd_info usb_sbc2410_info = {
?????? .port[0]??????? = {
?????????????? .flags? = S3C_HCDFLG_USED
?????? }
};

int usb_sbc2410_init(void)
{
unsigned long upllvalue = (0x78<<12)|(0x02<<4)|(0x03);
printk("USB Control, (c) 2006 sbc2410 ");
s3c_device_usb.dev.platform_data = &usb_sbc2410_info;
while(upllvalue!=__raw_readl(S3C2410_UPLLCON))
{
__raw_writel(upllvalue,S3C2410_UPLLCON);
mdelay(1);
}
return 0;
}
/***************************end add**********************/?

static void __init smdk2410_map_io(void)
{
s3c24xx_init_io(smdk2410_iodesc, ARRAY_SIZE(smdk2410_iodesc));
s3c24xx_init_clocks(0);
s3c24xx_init_uarts(smdk2410_uartcfgs, ARRAY_SIZE(smdk2410_uartcfgs));
s3c24xx_set_board(&smdk2410_board);
/*************************add by lfc****************************/
?????? usb_sbc2410_init();
/*************************end add*******************************/
}?


其實到了這里，要修改的代碼已經修改完了，比添加Nand flash的支持修改的地方還要少^_^，不過我一直以為還沒修改好，最后發現原來是沒配置好~_~

二、內核配置
下面說一下郁悶了我好一陣子的內核配置（支持USB）問題，這個就比Nand flash的配置要復雜多了。
１、讓內核支持熱插拔
?│??????????????? General setup? --->??
?│ │[*] Support for hot-pluggable devices

２、USB驅動設置，可能有些不選也行，不過沒時間去試，至于為什么要選這些選項的話可以看一下這個貼（Linux下的硬件驅動——USB設備）：

│ │??????????????? Device Drivers? --->?
│ │????????????? Generic Driver Options? --->???????????
│<*> Hotplug firmware loading support????
│ │????????????? Block devices? --->???
│ │????????????? <*> Low Performance USB Block driver???
│ │????????????? SCSI device support? --->???
│ │? <*>?? SCSI generic support??
│ │? [*]?? Probe all LUNs on each SCSI device????
│ │????????????? USB support? --->????????
│ │<*> Support for Host-side USB????
│ │[*]?? USB device filesystem?
│ │<*>?? OHCI HCD support??
│ │<*>?? USB Mass Storage support?
│ │[*]?? USB Monitor?
