Question

I'm working with the NXP LPC1788 microcontroller and I'm trying to create a driver on the host computer to communicate with it via USB. I believe that I've managed to get the device handling standard USB requests properly (the PC is able to read the string descriptors properly).

I'm having trouble writing a sample USB driver and installing it for the device, though. I'm working with Microsoft Visual Studio 2013. My steps were:

  • Creating a WinUSB Application, which produces a "Driver" and "Driver Package" project.

  • Modifying the generated INF file to use my device's VID and PID.

  • Building the projects - both build successfully. The output folder contains an INF file, a catalog file and WdfCoinstaller01011.dll.

  • Plugging in the microcontroller via USB, going to Device ManagerUpdate Driver Software..., browsing to the folder containing the INF file and selecting it.

  • This causes the following screen to appear:

  • I select "Install this driver software anyway". After a short while, it presents this screen:

My INF file is given below:

I tried out the INF template that Daniel K suggested here with my own configurations:

My device driver installed successfully and Device Manager reports that the device is working properly. I tried running my application and it's able to find my device and retrieve details about it. It all works now, and I can finally start working on the application-side of things.

Edit: Even though it's all working now, I have no idea what was wrong with the original template - could anyone please explain to me why the second template works and not the first?

OTHER TIPS

You're running 32-bit Windows, right? One reason the original file wouldn't work for you because it doesn't have a section for 32-bit drivers, it only has an NTamd64 section.

From the original file:

[Standard.NTamd64]
%DeviceName% =USB_Install, USB\VID_0483&PID_5720

From the new file, where MyDevice_WinUSB is analogous to Standard:

[MyDevice_WinUSB.NTx86]
%DESCRIPTION% =USB_Install, USB\VID_0483&PID_5720

[MyDevice_WinUSB.NTamd64]
%DESCRIPTION% =USB_Install, USB\VID_0483&PID_5720

The new file has an extra section that your old file didn't have.
