Didn't have to - already had that in my modprobe.conf. My issue is that 
the partition scan fails even for a single LUN device.

(shudder) yep, had first hand experience with that in the past. I 
completely agree with the safe approach.

Here is the one I am currently battling with - a multi-LUN thingy:

May 24 13:40:53 wookie kernel: Initializing USB Mass Storage driver...
May 24 13:40:53 wookie kernel: scsi0 : SCSI emulation for USB Mass Storage 
kernel:   Vendor: TwinMOS   Model: 7-in-1 Card RWCF  Rev: 0100
kernel:   Type:   Direct-Access  ANSI SCSI revision: 02
usbcore: registered new driver usb-storage
kernel: USB Mass Storage support registered.

kernel: Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0

Tomorrow will send you a few esoteric devices from office, including a 
Sony Clie that used to work just fine with usbstorage before (but not 
on FC2/linux 2.6.5), a couple of cameras and every card reader I can lay
my hands on. :)
