Hi. Thank You all very much for trying to help.
I have installed libusb-win32 device driver.
Here is the printout from the TestLibUsb program which is provided with the
driver.
It still doesn't work. My main problem is that I don't know what the error
means and I had no luck finding in online.
Thanks.
