I see a 3X drop in thruput, ouch, when I substitute ub.ko for usb-storage.ko.
Specifically I get 0.5 GB/min from ub.ko, as contrasted with 1.5 GB/min from usb-storage.ko, in the outside 1 GiB of a particular disc, in three or more consistent consecutive samples from each.
I knew how to patch to allow bytes/LBA != 512 only because of your recent answers in [usb-storage]. I took my samples from linux-2.6.9-rc1-bk2, modprobe'ing .ko built with and without CONFIG_BLK_DEV_UB.

Yes please.
Even DVD-RAM need the ioctl's to pass thru SCSI, for everything vendor-specific that lies beyond generic read and write.
