When I'm using the npxusblib with the USE_USB_ROM_STACK USB_Init() isn't configuring USB controller (interrupts are not turned on in the controller). Looks like the USBD_API->hw->Init in UsbdRom_Init() doesn't work properly but it returns LPC_OK. USB ROM Stack isn't working even if I configure the USB Controller by hand. I'm using the LPC4357 OEM Board produced by Embedded Artists. Have anybody had the same problem? Sorry for my poor english.

You are right! I haven't noticed it. It is here http://www.nxp.com/documents/user_manual/UM10503.pdf on the page 644. I must not ignore introduction parts of manuals. Thank your very much.

I've used it before for DFU class on a number of 18xx/43xx devices and haven't had any problems with it.
Maybe the DFU USB (ROM) examples in LPCOpen may help?

I remember reading the documentation and not being 100% clear on whether the USB ROM stack was even preset in the flash parts.  If you read it literally it seems to imply that this is only present on the LPC4330 and LPC4350.  Maybe someone else can confirm/deny?  Because I'm curious too.
