    sys/dev/usb          ehci.c ehcireg.h 
  MFNetBSD ehci.c and ehcireg.h
  ehci.c (1.55), ehcireg.h (1.16); author: mycroft
       Set the data toggle correctly, and use EHCI_QTD_DTC.  This fixes
       problems with my ALi-based drive enclosure (it works now, rather
       than failing to attach).  Also seems to work with a GL811-based
       enclosure and an ASUS enclosure with a CD-RW, on both Intel and
       NEC controllers.
       Note: The ALi enclosure is currently very SLOW, due to some issue
       with taking too long to notice that the QTD is complete.  This
       requires more investigation.
  ehci.c (1.56); author: mycroft
       Failure to properly mask off UE_DIR_IN from the endpoint address
       was causing OHCI_ED_FORMAT_ISO and EHCI_QH_HRECL to get set
       spuriously, causing rather interesting lossage.
       Suddenly I get MUCH better performance with ehci...
  ehci.c (1.58); author: mycroft
       Fix a stupid bug in ehci_check_intr() that caused use to try to
       complete a transaction that was still running.  Now ehci can
       handle multiple devices being active at once.
  ehci.c (1.59); author: enami
       As the ehci_idone() now uses the variable `epipe'
       unconditionally, always declare it (in other words, make this
       file compile w/o EHCI_DEBUG).
  ehci.c (1.60); author: mycroft
       Remove comment about the data toggle being borked.
  ehci.c (1.61); author: mycroft
       Update comment.
  ehci.c (1.62); author: mycroft
       Adjust a couple of comments to make it clear WTF is going on.
  ehci.c (1.63); author: mycroft
       Fix an error in a debug printf().
  ehci.c (1.64), ehcireg.h (1.17); author: mycroft
       Further cleanup of toggle handling.  Now that we use EHCI_QH_DTC,
       we don't need to fiddle with the TOGGLE bit in the overlay
       descriptor, so minimize how much we fuss with it.
