I bought a Serial to USB connector for a device that i want to connect with my laptop since my laptop does not have those Serial port that usually came with Desktops. So when i insert the cable and installed the driver, the program that i want the device to connect it with says :"Failed to open COM 1".
Well i don't know what to do now. The driver is installed, the LED indicator that came with the device is blinking (for a while) but the program says otherwise.
