You can get more information by turning on the USB Mass-Storage verbose debugging option in the kernel configuration (CONFIG_USB_STORAGE_DEBUG) and rebuilding the usb-storage driver. That will add lots of debug info to the dmesg log when you plug in the device. Also make sure that SCSI logging is configured on.
