USB modem mode switcher

I got a 3G modem similar to the one that is on the picture. The problem is, the modem vanished from Device Manager each time I restarted my laptop. It didn't work unless I started the Chinese software application which was loading it.

After wasting some time trying to load it without the Chinese loader, I found out that such modems work as a virtual CD ROM device when inserted and do not expose any ports or the modem interface.

The loader gives them an eject command which changes their mode from storage to modem mode.

Here is a mode switcher for USB modem that can be used to load such modems at start up.
