I don't think you've shown a relevent part of your dmesg. The reader 
should hopefully be recognised as a umass device. Do you see any umass 
devices in your dmesg? I don't see anything here but USB controllers 
(usb devices) or USB hubs (uhub devices).

Perhpas try typing 'usbdevs -d' for information on what devices have 
attached to what hardware.
