Take a look at this link: Intel® Quark™ Microcontroller D2000 - OpenOCD fails to start with ERROR : ‘Error: libusb_open() failed with LIBUSB_ERROR_ACCESS’, another user had the same issue, the user just re-installed the driver and it worked, so I recommend you to do the same.
In my case it worked at the first time, I connected the board and I went to the C:\IntelSWTools\ISSM_2016.x.xxx\tools\debugger\driver directory, I double clicked the install.bat and I answered 'y'. I checked the driver in the device manager and OpenOCD JTAG device appears on the Universal Serial Bus devices category and I was able to flash the ROM without problems. The only difference is that I have Windows 8.1.
I personally recommend you to try to re-install the driver, if it doesn't work send me a screenshot of the error that you are getting to assist you in a better way.
I hope you find this information helpful.
