I have fixed a few places that might have caused the timeout problem.
Could you download the new code and try again? Would you also add these
debug options to your config file?

options         CAMDEBUG
options         CAM_DEBUG_BUS=-1
options         CAM_DEBUG_TARGET=-1
options         CAM_DEBUG_LUN=-1
options         CAM_DEBUG_FLAGS="CAM_DEBUG_INFO|CAM_DEBUG_TRACE|CAM_DEBUG_CDB"

Add this entry to the xpt_quirk_table in cam/cam_xpt.c,
        {
                { T_WORM, SIP_MEDIA_REMOVABLE, "PINNACLE", "RCD*", "*" },
                CAM_QUIRK_NOLUNS, /*mintags*/0, /*maxtags*/0
        },

Thanks for trying the driver out, I really appreciate your patience. Since I
don't have the hardware myself, I have to rely on your help.

Thanks
