Is your project based on lpcopen demo ? if yes which one? any revise ?

Please track where runs to error? Does it enumerate well?

Hi,

I am trying to interface the USB barcode scanner. I am using the LPCOpen Keyboard Host example, I am getting the keyboard keys. But when I connect the barcode scanner, it shows device is enumerated, but now able to read the barcode data. Can you please let me know, what modification need to be done in the keyboard code example to read the barcode data. 

Controller LPC4337

Barcode Make Newland.

Model NLS-HR11

Warm regards.
