Thanks for the log.

If you go to 
Device Manager > AVR ISPMKII > Properties:

1) Can you confirm the Driver Name and Date/Time 
2) Do you have the same issue in Arduino IDE?
3) Have you installed Atmel Studio? (DONT Install it if you haven't as it can alter the USB Driver)

Hi,

If you have never installed atmel studio then the usb driver that came in the box with the mkII should have worked.

avrdude.exe is the program that atmel created for software such as Arduino IDE and Visual Micro. Unfortuently the usb driver atmel programmed avrdude for is different to the one installed by atmel studio. Therefore when we hit this issue it is usually because atmel has been installed and overwritten the driver that avrdude needs to perform the upload with mkII.

You are using the Arduino IDE in a small way already. The toolchain your Uno is mapped to is installed when you install the Arduino IDE. You can see the AVR toolchain below this folder on your pc "C:\Program Files (x86)\Arduino\hardware\..."

To upload via the mkII Visual Micro does no work at all other than running the following command. You can run the same command from a cmd prompt.

C:\Program Files (x86)\Arduino\hardware\tools\avr\bin\avrdude "-CC:\Program Files (x86)\Arduino\hardware\tools\avr/etc/avrdude.conf" -v -V -patmega328p -cstk500v2 -Pusb Hzatmega328\Debug/WaterFlowMeter_LORA.ino.hex:i"
 

Simon suggested you try the same upload in the Arduino IDE. It will prove to you where the issue is and remove some of the "unknown" for you about how uploads are executed. Creating a simple sketch in the arduino ide, setting the correct mkII programmer and then clicking "Tools>Upload using Programmer" should show the same error you are seeing in Visual Micro. When you search for solution to an arduino ide problem in google you will find a wider community than for visual micro thus potential for more solutions. This is the reason Visual Micro remains Arduino IDE compatible.

The solution to this issue has always been around usb driver but it apears you have followed the guides but to no available. The only question mark we have is if avrdue is looking for known vid/pids of the Arduino Uno. The vid/pids of your Uno look like a clone and we have never tested mkII with a clone. That said it would be a surprise to us to hear that avrdude has an issue with clones, they usually work fine.

The results of you test in the Arduino IDE will be interesting to hear.

Thanks

You can override the default program pattern, using a Local Board.txt file.

This can be added from vMicro > Add Code > Add Local Board.txt

Then you will need the pattern to modify (which can be obtained from the build output, with the vMicro > Compiler > Show Build Properties enabled, and performing a build).

Add the modified pattern to the Local board.txt and try the upload again, something like the below:

tools.avrdude.program.pattern="{cmd.path}" "-C{config.path}" {program.verbose} {program.verify} -pm328p -cstk500v2 "-PCOMXX" -e -U "-Uflash:w:{build.path}/{build.project_name}.hex:i"
