USB switching to unwanted dev at boot

English Install/Boot/Login
1

Greetings,

when booting with Huawei E3372 USB stick plugged in, it is recognized as

New USB device found, idVendor=12d1, idProduct=14db

This devcice is NOT wanted.

However when i manually unplug and insert the USB devive it is recognized as

New USB device found, idVendor=12d1, idProduct=155e

This is the device I want.

I’m using usb_modeswitch 2.5.1 with
**EnableLogging=1
HuaweiAltModeGlobal=1
**
Is there a proper way to logically remove/insert a USB device via script?
Currently I’m using a script like

USB_DEV=1-1
echo ${USB_DEV} > /sys/bus/usb/devices/1-1/driver/unbind
sleep 10
echo ${USB_DEV} > /sys/bus/usb/drivers/usb/bind

USB_DEV is taken from a prevous dmesg

Thanks for reading and comments.

**"**By default, your linux box would register your Huawei E8372 as a Mass Storage device and not (somehow) as a modem. First, make sure you have the exact same device we’re talking about. This can be confirmed by looking at 2 values."

usb_modeswitch is the proper way and should run automatically. Reboot and before doing anything run as root

udevadm test -a add /sys/bus/usb/devices/1-1

Adjust device name as needed and post complete command and its full ouptut.

Ok, rebooted and udevadm test -a add /sys/bus/usb/devices/4-1

MAG-HP0:~ # udevadm test -a add /sys/bus/usb/devices/4-1

…and I have no clue how to build the missing config file for usb_modeswitch :frowning:

It’s a HuaweiE3372

I presume all products are to be configures similarily (see comment at the link “I edited according to my Huawei E303”). Change values at Huawei E8372 Linux Configuration and Setup · GitHub according to your HuaweiE3372.

usb_modeswitch primary configuration is for switching from virtual CD-ROM to modem mode. Your device is already in one of communication modes. My understanding is that 14db is HiLink (router mode) and 1506 is STICK (modem mode). Any reason you cannot use 14db?

Anyway, please, reboot with stick plugged in, unplug and plug back and provide full output of “journalctl -b” as root. Upload to https://susepaste.org

I’m using modem mode 155e providing /dev/ttyUSB0 - 2 for SMS traffic.
I cannot use 14db HiLink.

This sounds very similar to E3372h-320 (update 2020 version of E3372) automatically switches itself into ethernet mode. Try adding suggested quirk, make sure to run mkinitrd after creating this file because usb-storage is loaded in initrd already.

journalctl unplug/plug USB: SUSE Paste

It is more or less the same, except this time usb_modeswitch is the first to run. As it is apparently race condition, it can explain why it happens during boot (modem has more time to initialize its firmware).

For testing you could also try to disable usb-storage completely (see the same thread).

Thanks to all for your helpful comments.

It finally turned out that by removing the usb device **CD-ROM ASUS **my issue is solved.
The USB stick is recognized as 12d1:1f01 and usb_modeswitch comes inot action and switches it to 12d1:155e.

As arvidjaar mentioned, it’s likely a race condition.

Thanks for your time!
