Is this right??? "simulation"? The usb storage spec is scsi commands sent over usb. Nothing has changed there. But yes, if you really don't want your usb device to use the scsi code, there is a driver, ub, in the 2.6 kernel that will do this for you. Be forewarned, it is slower than the usb-storage driver.
