(SOLVED) Помогите, пожалуйста, настроить Cmotech CNU-680 !!!

Люди добрые, на данный момент есть сей девайс http://skylink.ru/pages/equip.aspx?id=16154&r=77
После продолжительных рысканий в нете по этому девайсу узнал, что в сем устройстве интегрированы два девайса: сам CDMA момед и флешка на 50Мб. Как некоторые уже догадались, проблема в том, что не могу я переключиться с флешки на модем.

вывод dmesg'а гласит:

Bus 002 Device 005: ID 16d8:6803 CMOTECH Co., Ltd. CNU-680 CDMA EV-DO modem

знаю, что в моей ситуации может помочь usb_modeswitch и udev правила. но ввиду того, что я пока не очень силен в линуксах, прошу вашей помощи непосредственно в настройке, или подскажите с документом, описывающим данный модем.

заранее всем спасибо
