jBiDiB jbidibc USB POM Install the libusb drivers for using the libusb access. Under Windows OS you must install the Zadig driver as described here: https://github.com/libusb/libusb/wiki/Windows. Zadic can be downloaded from: http://zadig.akeo.ie/ In the Zadig UI you must check Options > List all devices and the select the 'USB-EPP /I2C... CH341A' device. Then select the target driver with the spinners (I used libusb-win32 (v1.2.6.0)) and click the 'Install driver' button.

The newest version!
