i am having a flip flop usb modem which has two modes

1 usb mass storage mode:

root@devbox:/media/F872F0FD72F0C184/Users/idlecool/Downloads# lsusb
Bus 006 Device 003: ID 19d2:fff5 ONDA Communication S.p.A.

2 usbserial mode:

root@devbox:/media/F872F0FD72F0C184/Users/idlecool/Downloads# lsusb
Bus 006 Device 003: ID 19d2:fffe ONDA Communication S.p.A.

by default whenever i plug the modem to the usb port.. the linux machine recognize it as a usb mass storage device.. how can i make it load as usbserial device

i have been using a package usb_modeswitch in the past on ubuntu 10.04 but i cannt install the same package on gentoo live cd.. even udev is not installed on live cd.. how to change the product-id of the usb device on gentoo live disc without udev.
