How comes my modem gets switched when plugged during boot?
This post is inspired by a similar question made by a Linux user. Exact question answered by this post is:
When my USB modem is plugged during boot, it gets switched, although modem-modeswitch, Usb-ModeSwitch and Sakis3G are not installed on my system. How is that possible?
Some modems automatically switch mode (and, most of them, their product ID along the way), on their own (without the need for Usb-ModeSwitch), when they are simply "ejected". Reason we call it "eject" is that they indeed actually "fool" computer/operating system into presenting themselves as USB CD-ROMs (their commercial name now turns relative: "ZeroCD"). When those pseudo-CD-ROM devices receive the "eject-your-media" SCSI command, they instead switch mode, and become usable as modems.
Some others, switch mode (again, on their own), if being plugged on computer for some seconds (e.g. modem might switch on its own after 60 seconds of inactivity have expired). This one case is self-explained and we will not bother more on this post.
