Following things are description for *usb-modeswitch *got from synaptic *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* *Linux kernel module, such as "usbserial". However, the device still* *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".*
In the above paragraph they says if the device is not detected as a model then we can use this tool. But in my case the device is getting detected as modem device (The network manager window is popping up when I pug in the device..)
