Log message:
from netbsd, ohci.c 1.142 1.147
log message for 1.142:
Fix a done list handling bug which exhibits under high shared interrupt
rate and bus traffic.  As the interrupt register is read after checking
hcca_done_head, there was a small chance of dropping a done list.
Ignore OHCI_WDH interrupt bit if hcca_done_head is zero so that OHCI_WDH
is processed later.

log message for 1.147:
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.
