RE: [MM] Problem Huawei E303

I'm not sure if this list allows attachments.
I send two log files attached:
ndis.txt -- System logs (ModemManager in debug mode) of an unsuccessful NDIS Huawei connection attempt.
attachmodem-txt -- ModemManager logs where the usb modem is not detected the first time it is plugged in the 
computer, the second time the MM detects it.

If you need more logs don't hesitate to ask for them.

Thanks for your fast response! and thanks for the new NewtorkManager packages. I have installed them and 
they seem to work fine.

I was using a Git version from the 18th. This morning I have updated my local version with the latest 
version from the repository.

I have tried with the Huawei e303 modem and it tries to create an NDIS connection, but it doesn't work.
So I have removed the net interface from mm-plugin-huawei.c

Now it always try to connect through pppd and it always works :) I haven't the port problem that the 
previous version has.
Has anyone been able to connect through NDIS with a Huawei modem? With which model?

Can you send us debug logs of MM while we try to use the NDIS port? We
added support for net ports very recently in the Huawei plugin, actually
Huawei themselves started that work and they tested it with different

I have found another issue that I am not sure if it is a bug or not. It seems that the ModemManager cannot 
detect the first time that I insert the modem.
After try with many ports it prints the next lines:

yet ('24.443516' seconds elapsed)

But If I unplug and plug it again it will recognize the modem.

Ah, my heisenbug. Yes, I've been the whole morning trying to reproduce
it after I saw it yesterday. We configure a timeout to be run 2s after
we initialize the device probing, but for some reason it doesn't get
fired. Nice to see that I'm not the only one seeing it, will try to
track it down these days. Do you have a full debug log of this issue
happening? Or just that snippet?
