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

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.
