CVS commit: src/sys/dev/usb

[David Young <dyoung%netbsd.org@localhost>]

Module Name:    src
Committed By:   dyoung
Date:           Thu Nov 12 20:11:35 UTC 2009

Modified Files:
        src/sys/dev/usb: uhub.c usb.c usb_subr.c usbdivar.h

Log Message:
Re-order operations in usb_detach() so that if a usb(4) instance's
children will not detach, the instance is not left in an inconsistent
state.

If uhub(4) port is disconnected, forcefully detach the children on
that port.

Simplify detachment hooks.  (sc_dying must die!)

Pass along and respect detachment flags, esp. DETACH_FORCE,
throughout.
