LPC2368 USB problem

Hi!

I am trying to make an USB HID application to work with a LPC2368 based board. I can get the PC to detect that the device is connected, but it doesn't receive the input reports. I think it is a hardware problem (I have tested my software in a MCB2300 board and worked perfectly), but as it is my first USB project I can't figure out what the problem is.

The board schematics are: pdfcast.org/.../fpga-board

I have already connected the D+ line to 3.3V using a 1,5k resitor.

Thanks in advance.
