Hello,

I put the code in a CVS branch "itohy-usb1".
Please test and debug.
I don't have many USB devices and I need your help.
(I only have some umass(4), a modem device ukyopon(4), and ukbd(4)/ums(4).)

To check out the kernel source tree,

1. check out checkout script
	cvs checkout -ritohy-usb1 src/sys/dev/usb/filelist
2. update files in the branch
	sh -e src/sys/dev/usb/filelist


Recent changes:
	ehci: done simple test
	ehci/ohci/uhci: fix power hook (untested)
	slhci: do not pass zero length to bus_space_*_multi_1() on
	    mbuf(9) transfer (untested)
	slhci: add pcmcia frontend (untested)
	API change: these functions will not fail without programming errors

-usbd_status usbd_map_buffer(usbd_xfer_handle xfer, void *buf, u_int32_t size)
-usbd_status usbd_map_buffer_mbuf(usbd_xfer_handle xfer, struct mbuf *chain)
+void usbd_map_buffer(usbd_xfer_handle xfer, void *buf, u_int32_t size)
+void usbd_map_buffer_mbuf(usbd_xfer_handle xfer, struct mbuf *chain)

	needed for slhci.
+void usb_buffer_mem_rewind(struct usb_buffer_mem *ub)
