Thank You for response. No, I didn't know that I need it :( I think, th=
at it is too complex for me - to install a special driver - for my simp=
le application. I only want to detect all connected USB devices... (Do =
I need a special drivers for all devices??? )... Is there any other way=
to reach this - detecting connected USB devices under Windows? Maybe w=
ithout libusb-win32? Does anyone know?
Wolek.

Download the DDK from Microsoft's web site and take a look
at the 'usbview' example. This may be what you are looking
for.
