I have a Nokia 6500C connected with PC by a CA-101 cable.
6500C set connection mode as "PC suite".
Then Pc has two COM ports connected the device,
COM3 as "Nokia 6500c USB" and COM4 as "Nokia GSM Phone USB Modem".
And the 6500C device has a COM port as "USB1".

StreamConnection conn = (StreamConnection) Connector

This program will throw a exception for "USB Used".

If I disconnect the CA-101 cable, this program will success.

The problem is I want to establish a connection from 6500c device and PC by com port.

Anyone can give me some suggestions?
