How to make EDGE USB Modem work in Linux?

In The Name Of Allah The compassionate merciful

Good day all ;
Have a EDGE USB Modem and want to connect internet with it .
It has a drive that contain a driver and windows users install it and go ..

Someone told me use usb_modeswitch :

> mode switching data for usb-modeswitch
>
> Several new USB devices have their proprietary Windows drivers onboard,
> especially WAN dongles. When plugged in for the first time, they act
> like a flash storage and start installing the driver from there. If
> the driver is already installed, the storage device vanishes and
> a new device, such as an USB modem, shows up. This is called the
> "ZeroCD" feature.

> On Debian, this is not needed, since the driver is included as a

> shows up as "usb-storage" by default. usb-modeswitch solves that
> issue by sending the command which actually performs the switching
> of the device from "usb-storage" to "usbserial".

Now , don't know how to use usb_modeswitch ?
have read man and did so > sudo usb_modeswitch -v 05c6 -p 0015
=A0but result says #
Warning: no switching method given.
