- Some cleanup and improvements in the uhci and ohci drivers - Support for plugging and unplugging devices improved - Now available is bulk transport over OHCI controllers - Resume and suspend have been temporarily been disabled again. Proper support for it is available in the uhci.c and ohci.c files but I have not yet spent the brain cycles to use it. - OpenBSD now uses the USB stack as well - Add FreeBSD tags
