没有找到u盘。
2.加载模块
cd /lib/modules/2.4.x-x/kernel/drivers
insmod sd_mod.o 此为usb驱动
3.再使用fdisk或cat /proc/partitiongs查看结果如下：
[root@shangxinying scsi]# cat /proc/partitions

说明已经可以识别u盘了，设备名为/dev/sda1.
4. 挂载:
mount -t vfat /dev/sda1 /mnt/usb
但是这种方式下挂载的u盘上如果有汉字的话可能会显示乱码，可以用下面的命令解决该问题：
mount -o iocharset=cp936 /dev/sda1 /mnt/usb
5.谢载：
umount /dev/sda1
6.如果为了释放kernel资源想卸载模块：
rmmod sd_mod.o
