HOW TO - Manually Install Doser 2 Firmware driver
I see on the forum and get lots of requests on how to manually install the firmware USBVCOM driver which is required when doing updates. Windows 8 especially does not install this automatically.
Here is a step by step for Windows 8.1 (the basics should apply to most windows OS's)
1. Download the latest firmware from here to update the doser 2

Select Doser 2 and then go to the firmware folder. Download the ZIP file and then extract the MHX file to your desktop so it can be easily found for later. It is critical you extract the file.
2.Finding the Firmware tab in GHL Control Center - This is under Extras

3. Once you have clicked on firmware you will see this screen, just click next and your doser will go into Bootloader, the LED GHL sign will go dark.

5. Click on device Manager. What you are looking for is a COM port marked USBVCOM. It is likely instead you will see this (note the exclamation over the unknown device.)

Click (not open) the "DRIVER" folder to highlight it then press OK to select this folder. The driver will now install.
