USB data card not switching as modem

view story

http://forums.fedoraforum.org – I am new to Fedora. I have an INTEX Wireless Data Card Speed-3g V7.2 device, which i tried using it in F18. The OS recognizes it as a mass storage device( that is, it shows the drivers for Windows,Mac,Debian) but doesn't install it as a modem. I referred this post http://www.greplinux.net/2012/07/eve...now-about.html I tried switching it as a modem using usb_modeswitch but the device doesn't get listed under /etc/usb_modeswitch.d (according to the post, device has to be listed here so as to get his hex key). However the device is listed when using lsusb command without showing any brand (HowTos)
