insmod libcomposite.ko
insmod usb_f_mass_storage.ko
insmod g_mass_storage.ko file=/dev/mmcblk1p1 luns=1 stall=0 removable=1
这样操作以后，终端没有报错，但是连PC没有反应，是什么原因啊？如何解决？
/usr/ko # sh usb_storage.sh start
Mass Storage Function, version: 2009/09/11
LUN: removable file: (no medium)
LUN: removable file: /dev/mmcblk1p1
Number of LUNs=1
g_mass_storage gadget: Mass Storage Gadget, version: 2009/09/11
g_mass_storage gadget: userspace failed to provide iSerialNumber
g_mass_storage gadget: g_mass_storage ready
切换到host模式接鼠标可以正常工作，所以应该还是驱动的问题，USB口没有问题，所以会是什么样的问题？
