USB-CDC driver for Win64

Posted by rick drolet on June 24, 2011
Can someone point me to the Windows-64 driver to work with the FreeRTOS v7 CDC?

This is needed to replace the 32-bit usbser.inf dated Aug 18, 2009 with VID_FFFF and PID_0005

Thanks to all - figured this out.

If you have an answer, please post it here. Other people now on in the future will then have the information they need too.

Using this post as a guide, I used the inf file for the LPC134x_vcom.inf (32/64bit Mar 2011).

Within the file USB_CDC.c table abDescriptors, I just changed idVendor from 0xFFFF to 0x1FC9 (think is LPC) and idProduct from 0x0005 to 0x0003.

Note: While this makes this demo work for Windows 7 in both 32 and 64bit, this can only be a temporary solution as these IDs are registered to this specific manufacturer.
