华为 E3372 Mode_Switch 问题

我正在尝试切换调制解调器的模式，以便我可以在 Raspberry Pi 上访问互联网。

运行 lsusb 时：

lsusb
Bus 001 Device 005: ID 046d:c534 Logitech, Inc. Unifying Receiver
Bus 001 Device 022: ID 0a05:7211 Unknown Manufacturer hub
Bus 001 Device 021: ID 12d1:14fe Huawei Technologies Co., Ltd. Modem (Mass Storage Mode)
Bus 001 Device 018: ID 0a05:7211 Unknown Manufacturer hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

mode_switch.config 如下所示

 # Configuration for the usb_modeswitch package, a mode switching tool for
# USB devices providing multiple states or modes
#
# Evaluated by the wrapper script /usr/sbin/usb_modeswitch_dispatcher
#
# To enable an option, set it to "1", "yes" or "true" (case doesn't matter)
# Everything else counts as "disable"


# Disable automatic mode switching globally (e.g. to access the original
# install storage)

DisableSwitching=0

# Disable check for MBIM module presence and configuration globally (to aid
# special embedded environments)

DisableMBIMGlobal=0

# Enable logging (results in a extensive report file in /var/log, named
# "usb_modeswitch_<interface-name>" and probably others

EnableLogging=0


# Optional increase of "delay_use" for the usb-storage driver; there are hints
# that a recent kernel default change to 1 sec. may lead to problems, particu-
# larly with USB 3.0 ports. Set this to at least 3 (seconds) in that case.
# Does nothing if the current system value is same or higher

SetStorageDelay=4
DefaultVendor=0x12d1
DefaultProduct=0x14fe

TargetVendor=  0x12d1
TargetProduct= 0x1506

之后我运行 sudo usb_modeswitch -s 15 -I -H -c /etc/usb_modeswitch.conf

我正在使用外部供电 USB 集线器上的调制解调器。请帮忙

  1. 打开mode_switch.config并启用以下标志：

    DisableSwitching=0

  2. 运行此命令：

    sudo usb_modeswitch -v 12d1 -p 14fe -V 12d1 -P 1506 -M '55534243123456780000000000000011060000000000000000000000000000'
