Good Afternoon, All
I am a seasoned (10 year) developer with both embedded and .NET programming experience but I am new to working at the Windows driver level. I am working on getting a bidirectional data link between a host PC and a device and would like to use WinUSB as the driver. I have downloaded Jungo’s USB WinDriver and got that working but the SDK is fairly expensive and I would rather use something that is free as long as it will work. The data link would only be used for configuration purposes and not for regular operation of the device. I will outline the steps I have taken thus far as well as provide a copy of the .inf file I am using.
- Downloaded the Microsoft “How-To” guide and read it.
- Downloaded Jan Axelson’s C#.NET application that included a .inf file
- Downloaded and installed the WinDDK (ver 7600.16385.0)
- Modified the .inf file (see file for changes)
- Created a directory, c:\WinUSB, and added the winusb.inf and winusb.cat file to the root. Then created \i386 and \amd64 subdirectories and copied the respective winusbcoinstaller2.dll and WdfCoInstaller01009.dll files to each directory.
- Plugged a USB-to-Serial dongle into PC but DID NOT install provided driver
- Attempted to install the driver manually by pointing to the c:\winusb directory but it just says “Cannot Install Hardware” because it can’t find the software.
Below is a listing of my .inf file. A couple of notes on it:
- I know I need to apply for Vendor ID and Part ID. I will do that when we get this working.

Now for a couple of questions:
- Is my .inf file correct? I have read lots of posts and I feel that it is correct. My only hesitation is that 90% of the posts I read dealt with a previous version of the WinDDK files. I was not able to find much on v1.9
- To install the driver, I just plug in a USB device and instead of using the provided drivers use the .inf file I created, right?
I feel that my error is something really small. Reading other peoples posts, it looks like they were able to get the driver installation process started, but it halted at some point due to an error. It just tells me it can’t find the software, which leads me to believe I either have the files in the wrong place or I am declaring there location incorrectly in the.inf file.
Any help/advice would be much appreciated!
