disabling USB hardware

[daniewicz]

My motherboard has USB support, but I do not own any USB hardware so I wish to disable the USB support when booting linux.

 

My original lilo.conf looked like this:

 

image=/boot/vmlinuz

label="linux"

root=/dev/hda1

initrd=/boot/initrd.img

append="resume=/dev/hda5 splash=silent mem=1000M"

vga=788

read-only

 

With this lilo.conf, from boot.log:

Jan 2 08:18:13 192 usb: Initializing USB controller (uhci-hcd): succeeded

Jan 2 08:18:13 192 usb: Mount USB filesystem succeeded

 

 

Next I created a new lilo.conf adding nousb

 

image=/boot/vmlinuz

label="linux"

root=/dev/hda1

initrd=/boot/initrd.img

append="resume=/dev/hda5 splash=silent nousb mem=1000M"

vga=788

read-only

 

Using this lilo.conf removed the above USB message from boot.log. However, a USB controller still shows up in MCC under Hardware

 

???

 

I realize my best option would be to disable USB support in my BIOS, but I can't find anything other than disable legacy USB support.

You might try commenting out the "install usb-interface" line from /etc/modprobe.conf.

Thanks for the response. Unfortunately, commenting out this line didn't help.

Put usbcore at hotplug's blacklist (if still using hotplug, of course- I do not). If you don't like messages about failing insmoding at bootup, put there as well uhci-hcd.

There's another method (changing the default udev rules), but it's not necessary.

Finally, why don't you simply disable USB support from system BIOS?

I can't find anything in the BIOS other than disable legacy USB support.

 

I will try your sugestions. Thanks.
