hy

I use a me909s-120 Modem on a Odroid Xu4 machine which works fine. On the Odroid as soon as I plug the Modem into the USB 5 new USB devices are recognized.
However when I do the same on my Neo Core 2 no USB devices are installed.
Here is the output of de dmesg after plugin the USB Modem:

Code: Select all

[  349.595673] usb 4-1: new high-speed USB device number 3 using ehci-platform
[  349.759045] cdc_ether 4-1:2.0 wwan0: register 'cdc_ether' at usb-1c1c000.usb-1, Mobile Broadband Network Device, 02:1e:10:1f:00:00


lsubs shows:

Code: Select all

Bus 004 Device 003: ID 12d1:15c1 Huawei Technologies Co., Ltd.


I also tried the usb_modesiwtch but this might only be needed with those USB stick with integrated SD-Card reader:

Code: Select all

sudo usb_modeswitch -J -v 0x12d1 -p 0x15c1


And also modprobe usbserial did not help:

Code: Select all

modprobe usbserial vendor=0x12d1 product=0x15c1


So can pls someone help me to initialize those USB connections?


PS. on the Odroid XU4 the dmesg looks like this:

here are also the usb-devices output of the Odroid XU4

and the Neo Core 2

I:  If#= 6 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=06 Prot=1b Driver=(none)


The main difference ist that for the last 5 "devices" on the Neo core 2 "none" is written where on the Odroid Xu4 "option"
