There isn’t (right now, at any rate) any sort of generic driver for
USB-type devices. Therefore, there isn’t any standard way of opening
handles in user-mode programs to access them.

If your USB device is of a type that has a standard driver (such as HID,
or audio, or something like that), there may also be a standard way to
access it from user mode. So tell us more about your device…

Dear Walter Oney,

My device is just a generic USB device, to which a standard driver can be
loaded.

There *is* no “standard driver”. You’ll have to write one, in which case
you’ll call CreateFile using whatever symbolic link or registered
interface you define in your AddDevice function.

You can use USBIO which is a generic USB driver. It allows you to open a
handle and to communicate with the device. It works with any USB device.

Check out http://www.thesycon.de/usbio/eng/dl_usb_l.htm
It is free.
