Huawei E3372 troubles

Post by otila » 12 Feb 2015, 22:21

setup goes ok, cyan light (no blinking), 83% signal or something, but I can't receive packets, ifconfig lists rx errors. If I knew how to enable more verbosity.

ConfigList: /etc/usb_modeswitch.d/12d1:157d
SCSI attributes not needed, move on
Check config: /etc/usb_modeswitch.d/12d1:157d
! matched. Read config data
Use config file from override folder /etc/usb_modeswitch.d
Logger is /usr/bin/logger

Verbose debug output of usb_modeswitch and libusb follows
(Note that some USB errors are to be expected in the process)

Re: Huawei E3772 troubles

Post by otila » 13 Feb 2015, 00:31

I tried the E3772 on another box, it also had Fedora 21 (with only Fedora 21 packages), and it worked (dl about 35 Mbps)! However, it automatically used cdc_ether and got 192.168.8.x IP address, I would like to get the public one. My non-working box where I want to get it working has newer usb_modeswitch NetworkManager etc packages..

Where is it configured does it use ether or ncm?
I have Sonera Opengate.

Your E3772 is a Win8 cdc_mbim device which can also be switched into cdc_ether compatibility mode for older Win version.

usb_modeswitch will detect mbim dongles by their mbim interface attributes, will check if the cdc_mbim driver is present in linux and if those criteria are met then config#2 will be selected.
The dongle will keep its initial usb id since it is not getting mode switched.

If those criteria are not met then usb_modeswitch will instead send a modeswitch message to the dongle which will switch it into compatibility mode and that will also change the dongles usb id.

mbim detection is working in usb_modeswitch from version 1.26, the cdc_mbim driver was introduced in linux 3.8 so those are the min requirement if you want to run in mbim mode where you get a public ip.

OK so mbim detection is working but I can't receive packets. How to fix or debug this?

I have no idea, but it is not a usb_modeswitch task to create a connection, usb_modeswitch has done what it should do and has silently left the arena at this point.

Make sure you have the latest mbim comm libraries (mbimlib/libmbim)and the latest connection manager (Fedora using NetworkManager ?).
mbimcli may be useful for command line debugging.

mbim+NetworkManager+ModemManager are latest. I wonder is there anything odd.
At least byte/packet/error counters are all zero, but ifconfig shows non-zero values.
