How to "disable zero CD" in order to get my USB mobile internet dongle working? <SOLVED?>

Hello Tony, Nils, Sinclair and Everybody Else

While I started writing this message, I "suddenly" managed to
establish the mobile internet connection. Correcting one of the
provider specific codes in Network Manager was enough to get the
connection via the dongle running. However, I would like to evaluate
now what I need to do or not to do in order to keep this connection
properly running. Below, I work out this question in more detail.

Apparently you are right Tony:although the dongle is being mounted as
a "zero CD", the internet connection is working now. However, I am
wondering whether is better or not to:
each time "unmount", "eject" or "release" it, or....
to change the settings in such a way that the dongle will not be
mounted any more as "zero CD"
Or is this simply not relevant?

>> OS: dual boot Kubuntu Lucid and Win7.
>> Dongle: HUAEI E1820.
>> Netbook/ laptop: Eee PC 1001HA, 250GB HD, 1GB RAM.
>> Test result: at the Windows partition, the dongle works
>> automatigically, at the Linux partition still not.

Provider: T-Mobile NL, . Other
provider-specific specifics:
Number (for accessing the dongle): *99#
APN: internet
Account Name: tmobile
Password: tmobile
Additionally, I also have given in the PIN and PUK codes.

In the mean time, I one time restarted the netbook in order to test
the connection. And yes: also after this restart, the mobile internet
connection seems to work properly.

My dongle is being mounted as follows: /media/T-Mobile/
It also has Windows software.

As I said: the connection started working after giving in the correct
phone number meant to access the dongle: *99#
After a first restart, the connection continues properly working.
However, I have adapted some settings the past few days - but I am not
sure which of those adaptations were relevant. I would like to
evaluate which settings are essential to ensure a properly working
mobile internet connection.

See above.

The lsusb test delivers the following outcome with respect to the dongle:
Bus 001 Device 003: ID 12d1:14ac Huawei Technologies Co., Ltd.

"Connected and not connected": do you mean in this context: mounted or
not mounted?

The weird thing is now, that my dongle seems to work even while it is
mounted as zero cd.
Respectfully yours,
