HOST DEVICE DRIVER INSTALLATION
When connecting the target USB device to a host PC for the first time, the Hardware Update Wizard will ask you to connect the new device driver. You must install the new device driver at your own risk.
First, connect your USB device to the host PC. The Hardware Update Wizard will ask you for a new device driver. Ignore this window for the moment. Instead, open a Windows Explorer window and double-click c:\cygwin\lib\inf-wizard.exe. In its window, select 0x1384 and click the Next button. Click the Next button again and save the file as usb-ko.inf. Now, go back to the Hardware Update Wizard window and select “install from a list or specific location.” Check the “include this location in the search” box. Click on the Browse button and browse to c:\cygwin\lib\libusb. Finally, click on the OK button to continue. You have now successfully installed the generated device driver on your host PC. Two important files, libusb0.dll and libusb0.sys, have been installed by the Hardware Update Wizard.
