This is a continuation of the issue stated in USB LTE modem "Brovi E3372-325" not working
I have a similar issue as LaurentF.
When I try to use the following udev rule
# This is part of USB_ModeSwitch version 1.x.x
#
ACTION!="add", GOTO="modeswitch_rules_end"
SUBSYSTEM!="usb", GOTO="modeswitch_rules_end"
# All known install partitions are on interface 0
ATTRS{bInterfaceNumber}!="00", GOTO="modeswitch_rules_end"
# only storage class devices are handled; negative
# filtering here would exclude some quirky devices
ATTRS{bDeviceClass}=="e0", GOTO="modeswitch_rules_begin"
ATTRS{bInterfaceClass}=="e0", GOTO="modeswitch_rules_begin"
GOTO="modeswitch_rules_end"
LABEL="modeswitch_rules_begin"
# Huawei E3372-325
ATTRS{idVendor}=="3566", ATTRS{idProduct}=="2001", RUN+="/sbin/usb_modeswitch -v 3566 -p 2001 -W -R -w 400"
ATTRS{idVendor}=="3566", ATTRS{idProduct}=="2001", RUN+="/sbin/usb_modeswitch -v 3566 -p 2001 -W -R"
LABEL="modeswitch_rules_end"
I find that my device never has a bDeviceClass == "e0" or a bInterfaceClass == "e0" and thus the usb_modeswitch is never run.
When I run them manually, it failes, in the same way as for LaurentF.
Anyone an idea how I should try to debug this?
