CDC/ACM and PL2303 device drivers:  Don't use the max packet size assigned to an endpoint in order to determine the request buffer size.  The endpoint has not yet been configured that max packet size may be wrong.

SAMA5 UDPHS:  More USB fixes mostly related to byte counts, endpoint configuration, and dma configuration

STM32 Timer Register Bit Definitions: Some CCER bit settings changed per SourceForge bug #18 submitted by CCCTSAO

SAMA5 UPPHS: Fix a small mountain of compilation errors.  Still things to REVISIT so it is not ready for test

SAMA5 OHCI+EHCI: Using cp15_clean instead of cp15_coherent; EHCI: Need to set alt pointer in order to handle short transfers.

Add a new method to the USB host driver interface:  getdevinfo.  This method will return information about the currently connected device.  At present, it only returns the device speed.  The speed is needed by the enumeration logic in order to set a credible initial EP0 max packet size

SAMA5 EHCI:  Taking direction from wrong bit in SETUP request; need to flush data buffer before starting SETUP request
