2440在LINUX下模拟成U盘作为从设备与PC机通信

jayz

现在正在做2440开发板在LINUX下模拟成U盘作为从设备与PC机通信，也就是USB gadget驱动
通过2.6.13内核下2410_udc.c,file_storage.c得到加载的驱动模块
板子启动系统后：
[root@FriendlyARM udc]# insmod s3c2410_udc.ko
s3c2410_udc: version 28 Aug 2005
0.00 USB: s3c2410_udc_probe
0.01 USB: udc_disable called
[root@FriendlyARM udc]# insmod g_file_storage.ko file=/dev/scsi/host0/bus0/target0/lun0/part1 stall=0 removable=1
0.02 USB: usb_gadget_register_driver() 'g_file_storage'
0.03 USB: binding gadget driver 'g_file_storage'
0.04 USB: s3c2410_set_selfpowered()
g_file_storage gadget: File-backed Storage Gadget, version: 20 October 2004
g_file_storage gadget: Number of LUNs=1
g_file_storage gadget-lun0: ro=0, file: /dev/scsi/host0/bus0/target0/lun0/part1
0.05 USB: udc_enable called
然后将USB线插入PC机中，就没有反应了
0.07 USB: USB reset csr 0 pwr 8
哪位大侠能指点下吗
