That sounds to me like a power problem - the manufacturer probably thinks that
if you use a hub it will have a dedicated power supply rather than taking it
from the motherboard.
(This might mean that the device is taking more power than the standard allows.
They aren't going to admit to that, are they?)
You might find that a particular set of USB ports or headers on your motherboard
can supply more power than other ports. Your motherboard manual may help you
with this. Also, ensure that nothing else is using the motherboard port set you
connect the receiver to, thus diluting the available power.
