Huawei K3565 Rev 2: Randomly disconnects from mobile broadband network

Bug description:
I connect to a mobile broadband network through a Huawei USB 3G modem.
I stay connected all the time.
Every once in a while, with almost systematic periodicity (like every 20-30
minutes), without any apparent reason, whether or not I am using the network or
not, the nonnection suddenly goes down, and:
- the indicator shows I'm disconnected, the
- the mobile broadband networks (I have two of them configured, though I only
use one now) disappear from the list in nm-applet
- The option "Enable Mobile Broadband" at the bottom of the nm-applet menu
DISAPPEARS (not that it gets unchecked, it _disappears_ completely)
In order to reconnect I have to unplug and replug the usb modem, wait
a few seconds for it to be initialized or whatever, and then reconnect
via the nm-applet (when the nm-applet doesn't become unresponsive
because of another old known bug).
All the symptoms are EXACTLY as if someone had suddenly unplogged the
modem physically, so this may as well be a usb problem.
I have no idea what logs I should look for and attach.
