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.
