Bear in mind that your entire USB bus will reset when you hotplug a
device.  Meaning that the USB drivers may be reloaded by the hotplug
daemon.  So you may suddenly see messages for every attached USB device
and not specifically the one you just attached.

Do you have any attach messages?

Do you have any other USB devices connected?  That may not be your hard
disk.

Just for reference, my USB hard disk generates these messages when it is
attached:
Jan  3 07:05:08 Daneel kernel: Attached scsi disk sda at scsi1, channel
0, id 0, lun 0
Jan  3 07:05:08 Daneel kernel: SCSI device sda: 16992864 512-byte hdwr
sectors (8700 MB)
Jan  3 07:05:08 Daneel kernel:  sda: sda1


My USB card readers and floppy drive periodically generate these
messages until I insert media:
Jan  3 07:05:08 Daneel kernel: sdb: Unit Not Ready, sense:
Jan  3 07:05:08 Daneel kernel: Current 00:00: sense key Not Ready

Jan  3 07:05:08 Daneel kernel: sdb : status = 1, message = 00, host = 0,

I have that same entry in my messages but all of my USB devices work
perfectly.  I'm not really sure what it means.  It may or may not be
relevant.

Did you try what I suggested in the previous email?  The USB storage
device information will tell you exactly which storage devices are
attached and working:

$ grep Product /proc/scsi/usb-storage-*/*
/proc/scsi/usb-storage-0/0:      Product: USB 2.0 Storage Device
/proc/scsi/usb-storage-1/1:      Product: USB 2.0 Storage Device
/proc/scsi/usb-storage-2/2:      Product: USB Storage Device
/proc/scsi/usb-storage-3/3:      Product: USB FDC GOLD-1.30
/proc/scsi/usb-storage-4/5:      Product: ImageMate CompactFlash USB

Also, usbview will highlight entries in red if a device driver is
missing.
