host controllers to avoid the need to allocate any multi-page physically contiguous memory blocks. This makes it possible to use USB devices reliably on low-memory systems or when memory is too fragmented for contiguous allocations to succeed. The USB subsystem now uses bus_dmamap_load() directly on the buffers supplied by USB peripheral drivers, so this also avoids having to copy data back and forth before and after transfers. The ehci and ohci controllers support scatter/gather as long as the buffer is contiguous in the virtual address space. For uhci the hardware cannot handle a physical address discontinuity within a USB packet, so it is necessary to copy small memory fragments at times.
