Comment (by waddlesplash):

 Actually it seems the USB stack already handles userland areas:
 http://xref.plausible.coop/source/xref/haiku/src/add-
 ons/kernel/bus_managers/usb/Transfer.cpp#136

 It just doesn't do it when the kernel passes buffers in. So, we should
 modify this code to accept user buffers from the kernel, too.
