Does anyone know if the usb rom drivers are capable of supporting the media transfer protocol?

I have an application where an SDHC card will be connected to an LPC11U68, running FatFS on the processor to log data. It would be great to make the data on the SDHC card available via USB, but obviously using the mass strorage class runs into the host and local processor contending over the file system - not pretty!

The USB media transfer protocol may be a way around this, since the host is then effectively interacting with the local processor rather than directly with the file system.

Has anyone come across support for this class in LPCOpenWare?
