Usb "connection terminated"

HI

I installed a USM Modem and a Huawei E226 USB Mobile broadband modem
They all come with Vista x64 drivers
I do see them as installed on the device manager; but when I use thei
respective programs:
a) Mobile Partner (for the Huawei broadband modem), it appear
"Connection terminated" and "cannot find a phone-book entry"
b) Ipass roaming (for the USB Modem) or I'm trying to create a dial-u
connection
When I try to use the USB Modem, it says that there's no mode
available to create a dial up Connection
With the Ipass it doesn't show the modem on installed devices to use

I don't know what's happenning, but I'm getting crazy
For your information, either the USB Modem and/or the Huawei E22
worked perfectly on any other computer running Windows XP

Can anyone help me with thi issue or if you know how to solve it,
would appreciate it

I am running Windows Vista Hope Premium x86 64 bits

Thanks in advance
