Ok, something is going wrong in either hardware or kernel land for
this device.  You should be seeing entries like this from the kernel:

Nov 17 13:10:30 carcharias usb 1-3: new high speed USB device using
ehci_hcd and address 5
Nov 17 13:10:30 carcharias scsi2 : SCSI emulation for USB Mass Storage devices
Nov 17 13:10:30 carcharias usb-storage: device found at 5
Nov 17 13:10:30 carcharias usb-storage: waiting for device to settle
before scanning
Nov 17 13:10:35 carcharias Vendor: ST910082  Model: 3A                Rev: 3.02
Nov 17 13:10:35 carcharias Type:   Direct-Access                     
ANSI SCSI revision: 00
Nov 17 13:10:35 carcharias SCSI device sda: 195371568 512-byte hdwr
sectors (100030 MB)

Particularly the last one, about the new SCSI device and it's size, is
important.  If you have USB and the other drivers built as modules,
reload them and try again.  If they are built into your kernel,
reboot.
