Windows drivers - communicate with user process

I have written a application in Qt and what is the best way to communicate with a custom USB device (does not belong to any class - need to write custom drivers for it) under Windows. In Linux I could just share the data with user space from the /dev or /sys filesystems. What are the equivalent alternative in Windows ?

There are a couple of user-space USB libraries for Windows. While Microsoft do provide WinUSB directly, I'd recommend using either libusbx or libusb and installing the driver for your device with zadig.

Using libusbx rather than the Microsoft driver directly has the advantage of being easier to port to other operating systems, which might be a consideration for you as you are using Qt.
