嵌入式系统下挂载u盘出错!

Question

我的嵌入式CPU是S3C2410,内核版本是2.4.18

刚把U盘插上去显示如下:

[root@fa /]# hub.c: USB new device connect on bus1/1, assigned device number 2
scsi1 : SCSI emulation for USB Mass Storage devices
Vendor: Model: Rev:
Type: Direct-Access ANSI SCSI revision: 02
Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0
SCSI device sda: 503521 512-byte hdwr sectors (258 MB)
sda: Write Protect is off
Partition check:
/dev/scsi/host1/bus0/target0/lun0: p1 p2 p3 p4

然后我自己执行"mount /dev/sda1 /mnt/u",显示如下:

[root@fa /dev]# mount /dev/sda1 /mnt/u

mount: Mounting /dev/sda1 on /mnt/u failed: Invalid argument

请问哪里出了问题?

如果您不知道具体的解决办法,也可以给个方向,或者该看哪个方面的知识,从哪里下手比较好?
多谢了,您的任何建议对我来说都是有益的

以下是liulang_lu的回复,原谅我没有第一时间贴出来

mount /dev/scsi/host1/bus0/target0/lun0/part0  /mnt/u

使用ls命令看下/dev/scsi/host1/bus0/target0/lun0 目录有什么 ，然后如上面的命令挂载
