My computer says "unknown usb device (port reset failed)"

I have an Anker hub. I last port says the error. I have plugged the hub into every port on the computer and I get the same error. I tried the hub on 5 different computers and I get no error. The computer works fine otherwise. If I plug anything into the last port of the hub I get the error. This is strange.

I have factory reset the computer twice. I have uninstalled all the USB drivers and reinstalled them. I have disconnected and reconnected all my USB devices one by one and I get that error on the last port of that hub. 

I replaced the hub with another from Anker and the same thing happens with the new one. In fact, the first one was brand new. What's interesting is that although I get the error on the last port, I can still read and access whatever device I put on that port. For example, if I put an iLok on that port, I get the error but I can still license Pro Tools. If I connect a USB drive, I get the error but I can still copy and delete files as if there were no problem.
