I just had the exact same problem. I upgraded from 2.4.18 to 2.4.20. It 
took me a few hours to realize that the last line should have read:

input0: USB HID v1.10 Mouse [Logitech Trackball] on usb2:2.0

I took a hard look at my .config file, and there is a new option you 
need to enable:

CONFIG_USB_HIDINPUT=y

After some digging I found this was introduced in 2.4.19. I did not find 
documention suggesting to enable this when upgrading though. "make 
oldconfig" has this set to N by default. *sigh*
