I'm having trouble with the LPCLink drivers, I can get it working, but only after some manual exercises.

My configuration is: WinXP SP2

Is there a document somewhere that describes
- which driver should load (HID or WINUSB)
- should it be automatic or should it be manual driver selection
- when/why might I want or need to switch between drivers
- whats the difference between the HID and WINUSB driver
- what causes the DFU to execute and change the device to LPCLink in device manager
- what devices should I see under device manager at what point

I have figured out that I can manually execute the DFU from the command line and then I can only see the device under the HID driver.  At this point, I can get LPCxpresso to work.  But I don't understand why I can't get it to work automatically.  Some of the documents seem to indicate that WinXP should be using WINUSB.  What's the difference between the drivers?

I've searched all over the forums and code red's web site and embedded artists web site.  I've found many little bits and pieces, but I can't seem to find a single document that describes everything.

Try deleting the .launch files in your failing project. This holds the debug configuration. Maybe it has been corrupted?

I have a different project in the same workspace, and it works fine - loads the driver fine and starts debug session correctly.  With this working project, the I've tried both HID and WinUSB and they both work.

I think the problems started when I changed the project name in the Project Explorer.  I'm guessing there is a file somewhere that handles the DFU activation and possibly uses the project name somewhere, since my project name has changed, it's not finding what it needs.  The problem is, because there is no documentation on this process (or at least none that I have found) - I can't track the issue down.

Your configuration should be: WinXP SP3 ;)

I know about that link.  That's only part of the answer.  That tells you how to activate the debug code.  This IS where I saw that WinXP should be using WinUSB, but I can only get HID to work under WinXP
