No, not necessarily.
1. You can control *many* devices with the USB-UIRT if the devices are *different* devices (each respond to their own IR codes). This is especially true with the built-in blaster -- any device that can be reached by the blaster can be controlled. Also, plugging stick-on emitters in the back can allow you to control individual devices, since stick-on emitters are low-power and are basically only strong enough for the device they are stuck to.
2. If you need to control multiples of the *same* device, such as multiple of the same cable box, you would need to use the stick-on emitter approach, in which case, only 2 or 3 of the same device can be controlled (one for each channel or 'zone' on the USB-UIRT).
