Nothing. However that's only the messages concerning loading the
drivers. I think the messages about recognizing the hardware are
missing. Something like this (ohci, but uhci should be similar):

The last view messages are for my usb scanner.

Jul  1 23:10:01 hmg1 kernel: usb.c: registered new driver usbscanner
Jul  1 23:10:01 hmg1 kernel: usb.c: usbscanner driver claimed interface df9d9980
Jul  1 23:10:01 hmg1 kernel: scanner.c: 0.4.6:USB Scanner Driver

And here the scanner driver claimed the scanner.

Maybe 2.4 is more verbose than 2.2 but some messages about the hardware
should be printed. Maybe you have a ohci instead of an uhci host
controller? Or something else?

Bye,
