S5PV210 android2.2系统如何添加USB拔插自动识别？

我的系统已经在init.rc里创建了/mnt/udisk1，然后在vold.fstab文件里增加了：dev_mount udisk1 /mnt/udisk1 auto /devices/platform/s5pv210-ehci/usb1/1-1
还是不能识别U盘插入。插入后串口信息显示如下：
usb 1-1.2: USB disconnect, address 14
usb 1-1.2: new high speed USB device using s5pv210-ehci and address 15
usb 1-1.2: configuration #1 chosen from 1 choice

我看这个提示是kernel里的fat目录下的dir.c中的fat__get_entry这个函数发出的。

请问这是文件系统不支持fat32的原因吗？还是我android系统里的vold目录下的main.cpp没改的原因呢？
