Huawei ME906s: mbim transaction timeout

[Andreas Fett]

Hi,

for certain SIM cards (Vodafone Germany) and in certain Systems (ie.
Lenovo t460s) ModemManager seems to have trouble detecting the modem.

We have observed this for a couple of those combinations. Other SIM
cards seem to work fine and other thinkpad models aren't affected either.

The log shows a timeout during an mbim transaction. The expected reply
however seems to arrive after that.

Is there any other hint in the logs what might be the cause of this?

Andreas
