Are usb-uhci or usb-ohci loaded?  You need to have one of them loaded.  
It's possible to load usb-storage if the base USB chipset support isn't 
loaded.

That too.  If the base USB chipset support is loaded and the device 
isn't supported, you should see something like this in dmesg:

usb.c: USB device 2 (vend/prod 0x4102/0x1003) is not claimed by any 
active driver.

(the device above, an iRiver 390T mp3 player, is supported by libusb and 
the ifp-line project available on sourceforge, in case anyone was 
wondering--just not the usb-storage module!)
