You don't have the "usbmodules" program installed.
It's not necessarily "bad", it just means that the
hotplug events that were dropped on the floor while
your system was booting ("coldplug" events) couldn't
be recovered later. Workaround: unplug your USB
devices, then plug them in again.

Sounds like some sort of USB level problem. Are you sure
you have the right USB host controller driver loaded?
On 2.4 that'd likely be "usb-ohci", "uhci", or "usb-uhci".
