Thanks for your comment, I've tested some other products and found
their entries in /lib/udev/rules.d/40-usb_modeswitch.rules. So, does
usb_modeswitch comes with latest distributions by default?
Yes, it does. In most cases it is a prerequisite of Network Manager AFAIK.
The most-used mode switch entry in unusual_devs.h is there for
historical reasons, from a time when usb_modeswitch was not included
with distributions yet. I'm talking about "usb_stor_huawei_e220_init".
If people want to access the installer drive for some reason, it's not
possible if the kernel does the mode switch without giving a choice.
With usb_modeswitch, it's a matter of a small configuration edit.
