USB Console to Cisco Switch

I have download the Cisco program to configure my USB to COM port. The device can be detected in Device Manager.

When I open the terminal program and select the COM3 to access my switch, it prompt for

"Unable to open COM3. Please check your port settings:.

I have already changed it to another port COM4, COM5 but I still get the same problem. Any idea

Double check the serial port that is provided by the USB to serial.
Look in device management, com ports.

Try putty, and see if it lets you talk through the serial port? Do you have/use the Cisco serial-rj45 type console cable? Db9-rj45 console?
19200,stops bits 1, parity none?

Not all USB to serial work .......... For what you need.,

In fact, the cisco driver has been installed properly but it still  can't access the Cisco console port.

I also test the connection on a PC  with either  built-in com port and USB and  they return the same error message.

Try console cable and USB driver on Window 2008 server, it works perfect.

It seems that I can't make the connection on either Window 7 / 8. Something relate to OS... I guess.
