I am a newbie to USB as well as NXP.  I have two LPC11U demo boards:  LPCXpresso, and Keil MCB11U10.  I am trying to get either of them to speak on the USB port and get enumerated.  I would be thrilled to get a test application to talk to it.

Keil has a demo program that requires their RTOS.  I do not have that, and I prefer to use the NXP example.  I found on this site nxpUSBlib v0.98b.

It looks like I need to create a library before I can compile.  The readme provides instructions for how to do that in the section Keil uVision 4 IDE. 

The problem is, when I try to build the library, it compiles all that it needs, then chokes in the linker with the message error L6002U: Could not open file C:..\..\...\CDL_LPC11Uxx.lib: No such file or directory.

I confirmed that we do, indeed have the directory.  As for that file, I thought we were creating that.
Does anybody have any ideas?
