libusb_claim_interface error

[Arkwrite]

I tried to test PSY-Eye-Driver, but it doesn't work.

Firmware was successfully uploaded and libusbk was also installed.
But, (2484) res = libusb_claim_interface(handle_, 1); return -12 error.
Do anyone have any idea?

environment: Windows10 + VisualStudio 2013 Ultimate
Best.
