Hi,

I collect some information about this device, but I need some help:

The device looks like this:

T:  Bus=01 Lev=01 Prnt=01 Port=03 Cnt=01 Dev#=  3 Spd=480 MxCh= 0
D:  Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1

After

Code: Select all

usb_modeswitch -v 05c6 -p 98ff -S

it looks like this

I:  If#= 4 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage

But I afraid I have not the right module bindings.

Just

Code: Select all

echo "05c6 6001" > /sys/bus/usb/drivers/qmi_wwan/new_id
echo "05c6 6001" > /sys/bus/usb-serial/drivers/option1/new_id

is to much.

In windows the device switches to 05c6:6001

and the

device -numbers are:

00 for diagnostic
01 for modem
02 for application
03 for ethernet

I think there is one wwan-device to much, or it is completely wrong.

Any suggestions?
Should I try different modules too, if so which?

Regards,
Thomas

Starting ModemManager and NetworkManager - "connect".

IPv4/IPv6 works.

Thanks for the report Thomas, the id's will be added in the next data package release.
Can you please confirm that the dongle switches using -S (which is SierraMode), I had expected the dongle to either switch by itself or by using -K (which is StandardEject).

The USB Id 05c6:6001 after switching is likely a Qualcomm default id which remains because a sloppy Chinese mfgr didn't have an own id to replace it with.
This is the third 05c6:6001 variant I know of.

Self switching did not happen.

I tried already -K and eject /dev/sr0 both without effect. I haven’t sniffed the Windows driver.
So tried some messages from Qualcomm, -K -S and some others.

Because the result is the same as under windows I think the switching method must be ok.

And it works. In ppp-mode it did not work under Windows. Under Linux I have not checked, if modemmanager did hit the right port, but it did not work - at least under my test conditions.

The (qmi)wwan-interface works well, with IPv4 and IPv6 in 3G and 4G. It was not necessary to switch in raw-ip-mode.

I will check the support of raw-ip-mode later. But now I have found a working configuration, which looks like the mode under windows.

About the ID-chaos, no comment. If we run in conflicts, we will see it.
