This machine include USBKey and CD Sofware " Autolaser version 2.3.3, 1 USB Cable.

I did step by step like :
I use Win 7, 32 bit system!
Plug the USB Key, and then run to setup Autolaser Version 2.3.3, everything OK. After that i turn on the Laser machine and plug USB to my computer, but my computer just detect the laser machine like USB-EPP/I2C...CH341. I come back to the Autolaser software it cannot connect to the laser machine, when i click stark work it report link error!

As a software manual said that when i connect the machine to the computer, it will display " USB Serial Port (COM3)" but in my computer it does not.
This is my Pictures of main board!
