 It looks as if the USBD_NO_TSLEEP hack was accidentally removed
 during the big USB MFC. I believe that this is still needed in
 RELENG_4.
 
 Bringing it back may just involves undoing the small bits of the
 following revisions that mention that flag, though there might be
 more to it:
 
 	usbdi.h 1.21.2.4
 	usbdi.c 1.34.2.8
 	if_rue.c 1.2.2.2
 	if_aue.c 1.19.2.20
 	if_cue.c 1.7.2.7
 	if_kue.c 1.17.2.10
 
 It may be easier to reverse-apply the corresponding revisions from
 -CURRENT and fix the conflicts, i.e.:
 
 	cvs update -kk -j1.28 -j1.27 if_cue.c
 	cvs update -kk -j1.56 -j1.55 if_aue.c
 	cvs update -kk -j1.40 -j1.39 if_kue.c
 	cvs update -kk -j1.65 -j1.64 usbdi.c
 	cvs update -kk -j1.41 -j1.40 usbdi.h
 	(there is no suitable revision for if_rue.c)
