The probe code sends a path inquiry CCB (XPT_PATH_INQ) down to the controller driver to determine, among other things, the maximum target ID supported by the driver. The probe code won't probe any target IDs higher than the maximum target the controller driver claims to support. So check the driver and see what it is putting in the path inquiry CCB.
