Hi All,

I am working with Huawei E3372 dongle on linux-yocto-4.9. Version of Usb_modeSwitch is "2.2.0"

my device is not able to detect Huawei dongle automatically to usb modem. Instead of dongle get detected as storage device.
However, when I start usb_modeswitch manually, I am able to convert it.

Please help me with this issue

There were a lot of corrections and fixes since version 2.2.0. I suggest using the current version.

[ashish8292]

Sure, I will check on latest version also and will let you know. However, this version works fine with yocto kernel version 4.1.

Hi Josh,

I tried with 2.5.0 version and I can see that device is being converted but again it get disconnected automatically . Moreover, after disconnect why coverter is attached to ttyUSB1 instead of ttyUSB0.

You have a series of connect/disconnect and the most common reason for them is not enough power on the usb bus, the device resets itself and works until it connects to the tower when the added power consumption due to the transmitter being started creates a power dip.

usb_modeswitch does not create ttyUSBx devices, the kernel does and they are enumerated in ascending order. If you don't have any other serial devices on the usb bus then enumerastion should start with ttyUSB0 every time the device reappears after getting switched.

Both of the errors above could also be a chipidea usb controller driver error.

The E3372 that I have in my modem collection cannot connect via its serial ports. They only work as diagnostic ports. The connection is made through the NCM port, initiated and configured by AT commands sent as USB control transfers.

The "huawei_cdc_ncm" driver in the Linux kernel provides an interface to this; however I don't know if there are programs to use it aside from Network Manager.
