I was able to determine this was a problem by testing with both USB2.0 powered hubs and USB3.0 powered hubs.
Try replacing your hub with a USB3.0 hub. The worst case scenario is that you send the hub back to Amazon with free shipping because it didn't fix the problem. On the other hand, if it does fix your problem you've only lost the cost or opportunity.
This is wrong thinking, uSB 2.0 standard is 0.5A per port and that is what the BE was designed for. Yes many USB hubs are sold with an 'undersized power supply' but this is easy to calculate. The same is true for USB 3.0. Reason is there is no reason to assume anyone will actually use the full power per port (except for those insane bitcoin miners)
Example. PS is 2.0A Hub is 7 ports
2.0/0.5 per device = 4 BE will run reliable
RE power does not matter usb 3.0 or usb 2.0.
READ THE POWER SUPPLY RATING AND STAY WITHIN IT!!!! Note some of the usb hubs are sold and do not tell you in the add the amperage, just don't buy those. DUB-7 is very reliable, like $25, runs 6 be nonstop 3.0a ps.
