mcline,
In general we have found that most USB 3.0 ports will provide enough current to run the BB60C and VSG60 off of a single USB 3.0 connection. Where the second cable/connection is usually needed is on ultraportable laptops, ones that are optimized for low power consumption like the MS Surface Pro. I have not seen a port become damaged, but on those low power laptops, sometimes what you will see is Windows will shut off that port if it detects high current draw. It’s restored on a PC restart. If you have a machine that exhibits that, usually a powered hub is the best workaround.
When both connections of the y-cable are used, we don’t generally see any issues.
I would recommend the following 3 USB hubs, we know they work with our receivers and have been used to connect multiple devices simultaneously.

Let me know if you have follow up questions.
