Windows 7: USB modem Autorun is executed even Autoplay is disabled

USB modem Autorun is being executed even Autoplay is disabled

Here is good article about Autorun/Autoplay
Autorun vs Autoplay – What’s the Difference?

So if I get it, Autoplay is kind of bypass for autorun. If it is enabled (for all media and devices) autorun is executed, if it is disabled (for all media and devices) autorun is not executed.

I find out, that if I enable Autoplay (for all media and devices) in Control panel, autorun works on every device. If I disable Autoplay (for all media and devices) in Control panel, autorun is disabled for any device (CD, ext. HDD, USB Mass Storage, Phone configured as Mass Storage) except my USB modem (USB mobile broadband stick).
My USB modem ignores this setting and Autorun is executed anyway.
Om "My computer" window it is recognized as "CD Drive (I 3 Connect" as CDFS.
1. If on my PC is not installed Conection manager aplication, autorun runs setup wizard for Connection manager aplication. (even autoplay is disabled in control panel)
2. If on my PC is installed Conection manager aplication, autorun runs Connection manager aplication and I am ready connect to internet. (even autoplay is disabled in control panel)

I wanted to rename/delete Autorun.inf on USB modem, but it is protected. No change no write, only read.

Why I need to disable autorun.
I want to unlock E5830 modem. When I connect it to PC, autorun runs connection manager or setup wizard (depend if it is instaled or not) regardless of Autoplay setting. The USB COM port (COM57) is used by connection manager, so I can not establish connection between modem unlocker program and USB modem. When I close connection manager I can establish connection between modem unlocker program and USB modem. Then I run unlock process, but at the end of the unlocking process it requires modem reset (turn OFF and ON). At the end of the unlocking process, when the modem is turned ON, windows detects the modem device (as it would be pluged in) and autorun runs again connection manager (or setup wizard), what blocks COM57 port for modem unlocker program, unlocker program can not reestablish connection and unlocking process finishes with error. This happened to me with two different unlocker program. Both ofthem need modem reset. And that makes me trouble.

I wilcome any advices, how to solve it issue. Thanks in advance.
