Installing AVRISP mkII with Libusb-win32 on Windows 10

Enable Arduino `Program Bootloader` option

Its common that one needs to use a programmer from the Arduino IDE, but on Windows 10 things are not as simple. Many times the drivers installed are not correct hence the avrdude tool in the Arduino IDE refuses to work.

Here we would look at a way to make that possible.

The idea would be first to get the Libusb-Win32 driver installed which is essential for the avrdude to work.

Note: In case you have AtmelStudio installed this might have difficultly, due to the presence of the Jungo WinUSB driver. We would look into moving around that.

Let’s assume that on the PC we have the following situation:

  1. No drivers installed for AVRISP mkII
  2. We have Admin access
  3. We have internet available

Getting Libusb-win32

The libusb-win32 package available from Sourceforge.

We just need to download the latest available release version of the package.

Currently it is as on June 2018.

Make sure to get something on the similar lines.

If you do not find, just go the Files section of the Sourceforge and go to the libusb-win32-releases folder. Select the latest version folder and download the file similar to the above.

Setting Up Driver

Next, unarchive / unzip the Zip file as on June 2018.

Inside would be a directory structure similar to :


1. Open bin directory.

2. There in execute the inf-wizard.exe after connecting the AVRISP mkII.


3. Press the Next button.

4. Select the AVRISP mkII in the list


The Ids would be -

VendorID: 0x03EB

ProductID: 0x2104

Click Next to start the Ini creation process

5. Device Configuration

Do Not Touch this


Click Next to Proceed.

6. Save the INI file

Next it would ask to save an INI file with the name AVRISP_mkII.inf

Create A directory Named AVRISP_mkII-Driver.

Navigate to this directory and then Click on Save.

Next Click on Done to continue.

7. The Driver Directory

It should look something like


Disable the Driver Signing check

We would be disabling the Driver signing check temporarily.

  1. Hold Shift and select Restart from the Start menu. This would enter the advance setup mode.

  2. In Advanced Setup mode : Select Troubleshoot -> Advance Options

  3. In Advanced Options click on See more recovery options

  4. Next Startup Settings - This would reboot the PC and come to another reboot screen displaying options with function keys to select them.

  5. Press F7 this would select to Disable Driver Signature Enforcement - Again the system would reboot into normal windows.

  6. Now Open the Device Manager : Right click the AVRISP mkII under Other devices and select Update driver.

  7. Select the Directory Location where we earlier stored the generated driver.

  8. Windows 10 would show Warning about driver having no signature. Don’t worry its not a problem just select Install Anyway…

  9. Now you should be able to see libusb-win32 devices under which the AVRISP mkII is present in Device Manager

  10. We need to restore the Driver signing. Open an Administrator Command Prompt.

  11. In Administrator Command Prompt Type Command : BCDEDIT /set nointegritychecks OFF This would re-Enable the Disable Driver Signature Enforcement

  12. Reboot the PC normally.

Note: The Easy way to the enable and disable Driver Signature Enforcement Are 2 commands for an Administrator Command Prompt:

  1. To disable device driver signing, type BCDEDIT /set nointegritychecks ON then press Enter
  2. To enable device driver signing, type BCDEDIT /set nointegritychecks OFF then press Enter


This completes the Installation of the Driver.

Now we can try and check in the Arduino IDE if the avrdude interface works with AVRISP mkII

The generated Driver is included here.
