Does your system's BIOS support booting from USB devices?
It must support USB booting for this to work.
If it does, then you might also need a kernel patch for it to work,
except that it seems that your kernel isn't getting that chance.

I think that USB2 support isn't in 2.4.18, and even if it is, it's
quite aged.  Newer is better in this case.

Modules aren't required for hotplug support.  Yes, you can still remove
and add USB devices.
