usb_modeswitch在手动交换机上挂起

Question

我有3.2.27Linux内核和Busybox。我正在使用Raspberry PI。当我插入我的华为E303c dmesg显示

[    4.569781] usb 1-1.2: new high-speed USB device number 5 using dwc_otg
[    4.681078] usb 1-1.2: New USB device found, idVendor=12d1, idProduct=14fe

选件内核模块已在运行，但usb-storage模块未运行。但是当我进入usb_modeswitch -v 0x12d1 -p 0x14fe -H时，它挂起了，就像这样

Looking for default devices ...
 Found default devices (1)
Accessing device 002 on bus 002 ...
Using endpoints 0x04 (out) and 0x83 (in)
Inquiring device details; driver will be detached ...
Looking for active driver ...
 OK, driver found ("usb-storage")
 OK, driver "usb-storage" detached

有谁能给我一个解决方案，

这解决了我的问题

usb_modeswitch -c /etc/usb_modeswitch.conf -W -I

modprobe option
modprobe ppp_generic

我的/etc/usb_modeswitch.conf如下所示

TargetVendor=  0x12d1
