The FreeRTOS.org download includes a CDC driver (provided by a third party) 
for the SAM7.  When interfacing to Windows for the first time Windows just 
automatically recognised this and installed the CDC driver, so it must have 
a standard inf.  You could copy the descriptors for your LPC version (look 
in the lwIP/Rowley demo directory).

On my XP computer usbser.sys is in C:\WINDOWS\system32\drivers.
