Hi,
I have a problem with running a USB-CDC on the LPC1768. I have a USB circuit identical to the MCB1700 board. I use the sample code for USBCDC MCB1700 board. My program stops at the following line: while (! USB_Configuration); On the computer I get the message: "USB Device not Recognized." Is it a hardware or rather a software problem? Sorry for my English.
Best Regards, Lukas

If you would make an identical board as this entire schematic, and if you would run the sample code as is, it should work. http://www.keil.com/mcb1700/mcb1700-schematics.pdf
Then, you are telling lie.
For ambiguous question, just ambiguous answer comes. Make the effort to describe your problem well, if you expect helpful answers.
Post the schematic of your board.

I have two boards. These are my USB circuits:
