1714	"LFS-6.1.1: USB segfaults on ""legacy"" system"	Paul Rogers	Matthew Burgess	"This is a Socket-7 Pentium system with an unused header block for USB, support disabled in the BIOS.  Building module-inits-3.1 with book instructions (--prefix="""") put programs in /usr/local/..., --prefix=/ got them into /sbin, et al.  Booting produces the following errors:
./hotplug.functions: line 127: 1565 Segmentation fault   $MODPROBE -n $MODULE >.dev.null 2>&1
/etc/hotplug/usb.rc: line 122: ""X"" Segmentation fault   modprobe -q ""Y"" >dev/null 2>&1

Kernel is built with USB=off.  

It looks like init.d/hotplug looks for /etc/hotplug/usb.rc and then runs it with
""maybe-start"" which tries to modprobe usbcore assuming it's there.  Is that right?  But shouldn't it check for USB presence/support first?  Did somebody forget ""legacy"" systems don't necessarily have/need USB? /proc/bus/usb doesn't exist here--well, the 
BIOS has some support and the ports exist, I suppose."	defect	closed	normal		Book	6.1.1	normal	invalid	USB segfault
