This does sound like a power issue. The Doublesight monitors tend to use near 2x USB power, which is why they are shipped with a double USB cable, so nearly 1 amp each. If the PSU for the USB hub is only 2A, then it would power 2 displays, and the 3rd would have problems.

Plugable not only provide DisplayLink adapters, but they also provide USB Hubs, and have good support. It might be worth asking if they can recommend anything on their website:
