Firmware can not update

Good morning,

I bought the vertex k8400, yesterday I finished the complete assembly of the printer, I followed all the steps in the manual, when I get to install the firmware for dual head M1-V1.4-H2 with Arduino 1.0.6 on Windows 7 64 bit I get this message in arduino: avrdude usbdev-open did not find any usb device usb I followed the step by step procedure JPROG installed on the two pins.
IDE VCP driver 64 bits 2.12.06 installet.

Are there any solutions?
Thank You

Hi,
as far as I know, the dual head firmware is initially installed.
Only if you get a single head version, you have to change.
Please check, it is written in the documentation.

Did you install the USB/serial driver?

If so, connect your printer to an USB port on your computer and check if the Serial port shows in the Device manager (under Ports you should see : USB Serial Port (COMx)).

Check in Arduino under Tools/Serial port if the same serial port is selected.

Hi Raby

I install the USB/serial driver 2.12.06 64-bit.
Tools/serial in Arduine is the same serial port selected.
