Dear Chinthana, I understand this is a very old thread and I am sorry to ask my question this way. Since my problem relates to the same issue. I am unable to communicate with CJ1M CPU13. I have installed the USB driver, but the comm port doesn't appear in the Device Manager. As it was mentioned by you in this post that comm port driver should be installed separately and it was said that " So both drivers are included in the drivers folder and update the drivers for the unknown device by showing drivers folder. " I cannot find this driver folder. I received a driver CD with the cable and I have installed the USB driver from the CD. Could you please send me a link to the driver. Thank you, Regards, Abdul
