"LTE MIFI" won't switch modes

Post by wodgey » Thu May 16, 2019 10:04 am

I've got a "KuWfi 4g LTE unlocked USB dongle" (This one ---->>> https://www.amazon.co.uk/KuWFi-100Mbps- ... way&sr=8-9 )

and it won;t switch into Ethernet adaptor mode.

It has vid/pid of 161c:f010 when in CD mode and I have noted that in windows that it has 161c:f101 when in Ethernet mode.

When I use usb_modeswitch -v 161c -p f010 -W -K

Code: Select all

sudo usb_modeswitch -v 161c -p f010 -W -K
[sudo] password for roger:  
Take all parameters from the command line

 * Version 2.5.2 (C) Josua Dietze 2017
 * Based on libusb1/libusbx

AMAZING. That has caused progress.

It is looking like a Network Adaptor now but doesn't give me an IP address or show as an interface

That's because no driver has bound to the device.
Interface #0 is likely a serial interface and interface #1 is the network adapter interface, this is either a qmi_wwan
interface or a proprietary driver (not available in linux) interface.

What happens if you change the 70 in the switch msg to 71? Do you get a different interface layout?

I don't understand.

do you mean editing the message string to be this????

What happens if you change the 70 in the switch msg to 71? Do you get a different interface layout?
I don't understand.

do you mean editing the message string to be this????

Code: Select all

sudo usb_modeswitch -v 161c -p f010 -W -M 55534243123456780000000000000606f50402527100000000000000000000 
that has made no changes to ifconfig, only showing WLAN, LAN and LO
It is way to early for something to appear in ifconfig, did the verbose lsusb listing look same like before when you had 70 in the switch msg?
If you had a successful switch using 71 then I expect a different interface layout after switching..

ok, saw your edit. You got an additional interface, a mass storage interface for the built-in tf/sd card reader.
What if you change to 72?

Re: "LTE MIFI" won't switch modes

ok, so you have 2 configurations in the dongles firmware to choose between , one with and one without the usb mass storage interface, use the first one (70).

Afterh having switched the dongle then bind the serial driver (named option) to the interfaces:

echo "161c f101" > /sys/bus/usb-serial/drivers/option1/new_id

and show me the 8-9 lines from your dmesg where ttyUSB devices gets created by the above cmd.

Now you want to unbind the option driver from interface #1 and instead bind the qmi_wwan driver to it.

echo "3-1:1.1" > /sys/bus/usb/drivers/option/unbind

echo "161c f101" > /sys/bus/usb/drivers/qmi_wwan/new_id


If interface #1 is intended for qmi_wwan then you should be able to communicate with it.
You must have libqmi installed together with ModemManager and Network Manager.
Your dmesg log should show qmi_wwan and cdc_wdm binding to interface #1

You must have the modules option.ko and qmi_wwan.ko loaded in memory before you use their new_id functions!

modprobe option
modprobe qmi_wwan
modprobe cdc_wdm

then
lsmod to confirm they are loaded.
