Subject: (libusb) Fail to open USB device on Windows XP

Dear all,

While I use libusb-0.1.3-x86-mingw32 on Windows XP with the following
code

*******************************
require "libusb"
usb = LIBUSB::Context.new
device = usb.devices(:idVendor => 0x058f, :idProduct => 0x6387).first
handle = device.open
*******************************

I always get

'raise_error': LIBUSB::ERROR_NOT_SUPPORTED in libusb_open


In the code for 'open' (libusb.rb), it's written

You need proper access permissions on:
    Linux: /dev/bus/usb/<bus>/<dev>

Here are my questions:
1. Does my 'fail to open' comes from wrong access permission?
2. How can I solve this problem on Windows XP?

BR
Emmanuel
