Updating procedure huawei e220
For now, the only way I have network access is to revert to the 18.104.22.168 kernel, and use usbserial, instead of the option driver.IIRC, initially the device powers exposing a profile that includes a USB cdrom (designed for storing MS Windows driver software not required for Linux).Licence: GNU GPL version 2 Version: 0.4 Requirements: Linux Python py Serial Usage: ./(as root if necessary) Warranty: none!
Since the device is still blacklisted, I have no idea where the probe is coming from now.
network-manager recognizes the modem during a few seconds but disappear again.

After the update, my modem would continuously reset.
As part of my testing, I blacklisted the option module.
I reported a similiar bug a few days ago, but it was marked as duplicate.
