Well, see for yourself then:

/*
* The driver handles 3 Wire Protocols
* - Command/Bulk/Interrupt (CBI)
* - Command/Bulk/Interrupt with Command Completion Interrupt (CBI with CCI)
* - Mass Storage Bulk-Only (BBB)
* (BBB refers Bulk/Bulk/Bulk for Command/Data/Status phases)
*
* Over these wire protocols it handles the following command protocols
* - SCSI
* - UFI (floppy command set)
* - 8070i (ATAPI)
*
* UFI and 8070i (ATAPI) are transformed versions of the SCSI command set. The
* sc->sc_transform method is used to convert the commands into the appropriate
* format (if at all necessary). For example, UFI requires all commands to be
* 12 bytes in length amongst other things.
*
* The source code below is marked and can be split into a number of pieces
* (in this order):
*
* - probe/attach/detach
* - generic transfer routines
* - BBB
* - CBI
* - CBI_I (in addition to functions from CBI)
* - CAM (Common Access Method)
* - SCSI
* - UFI
* - 8070i (ATAPI)
*
* The protocols are implemented using a state machine, for the transfers as
* well as for the resets. The state machine is contained in umass_t_*_callback.
* The state machine is started through either umass_command_start() or
* umass_reset().
*
* The reason for doing this is a) CAM performs a lot better this way and b) it
* avoids using tsleep from interrupt context (for example after a failed
* transfer).
*/
/*
* The SCSI related part of this driver has been derived from the
* dev/ppbus/vpo.c driver, by Nicolas Souchu (nsouch at FreeBSD.org).
*
* The CAM layer uses so called actions which are messages sent to the host
* adapter for completion. The actions come in through umass_cam_action. The
* appropriate block of routines is called depending on the transport protocol
* in use. When the transfer has finished, these routines call
* umass_cam_cb again to complete the CAM command.
