It looks like it is well configured, because the usbfs and hub are loaded. You could check in your kernel configuration that you enabled USB Mass storage driver and attached a pen drive as I suggested before.
Another possibility is to insert a card in the USB card reader. Then you should be able to see with dmesg if it is recognized.
