Hello,
I am trying to use the USB_ROM_CDC example from the lpcware website
http://www.lpcware.com/content/nxpfile/sample-code-bundle-lpc11uxx-peripherals-using-lpcxpresso

the example compiles and runs fine on the chip(LPC11U37), the problem is that I cant find the .inf file to install the driver on windows 7 64 bits  Professional.

In Device Manager under Other devices I see that it is connected and called "LPC"
I try to browse to where the project is but there is no file for the windows driver.

Anybody help, where can I find the driver?

I tried goggling for it but no luck.

Mario

Thank you guys,
I manage to download the driver from the IAR example code bundle,
It installs the driver almost all the way but it throws an error:
"This device cannot start. (Code 10)"
After doing some research the closest answer I got was to make sure the PID and VID on the processor match and they do:

cdc_desc.c

ALIGN4 const uint8_t VCOM_DeviceDescriptor[] = {
  USB_DEVICE_DESC_SIZE,              /* bLength */
  USB_DEVICE_DESCRIPTOR_TYPE,        /* bDescriptorType */
  WBVAL(0x0200), /* 2.0 */           /* bcdUSB */
  USB_DEVICE_CLASS_COMMUNICATIONS,   /* bDeviceClass CDC*/
  0x00,                              /* bDeviceSubClass */
  0x00,                              /* bDeviceProtocol */
  USB_MAX_PACKET0,                   /* bMaxPacketSize0 */
  WBVAL(0x1FC9),                     /* idVendor */
  WBVAL(0x0011),                     /* idProduct */

  WBVAL(0x0100), /* 1.00 */          /* bcdDevice */
  0x01,                              /* iManufacturer */
  0x02,                              /* iProduct */
  0x03,                              /* iSerialNumber */
  0x01                               /* bNumConfigurations: one possible configuration*/
};

and the inf file:
lpc11xx-vcom_win7_64bit.inf

[DeviceList]
%DESCRIPTION%=LPC11xxUSB, USB\VID_1FC9&PID_0011

[DeviceList.ntamd64]
%DESCRIPTION%=LPC11xxUSB, USB\VID_1FC9&PID_0011

I am using the LPC11U37 processor and I am trying to use the USB_CDC ROM drivers

I have not altered the code from the sample code bundle in anyway.

What else could it be?

I just posted a blog with a .inf file that will work as well.

This may help
http://www.lpcware.com/content/forum/usbcdc-driver-installation-on-windows7

I know this is for LPC13, but the Windows driver is the same.
