Speculating here, but I wonder if the USB of the 11R is actually USB1(considering when it was introduced) and maybe that hammers the bus(remember that a FW400 interface can connect to a FW800 port but it only operates at FW400 speed(as will anything daisy-chained). Given the age of the 11R, I would look for an interfaced built for the speed of current computers and relegate the 11R to being the nifty guitar amp sim that it is
