Hello Miguel!

I hotplugged my pen drive to compare kernel messages.  It looks like
your usb_storage module is not loaded or not working.  Here is a bit 
of my dmesg:

scsi2 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 3
usb-storage: waiting for device to settle before scanning
usbcore: registered new interface driver usb-storage
USB Mass Storage support registered.
scsi 2:0:0:0: Direct-Access USB 2.0 Flash Disk 1100 PQ: 0 ANSI: 0 CCS
usb-storage: device scan complete
