Thanks but 1)Can you explain "Overpower"? 2)Given that power adapter is supplying 5V only,which is normally available in USB port & amount of current flow only depends upon how much an electronic parts needs, why should it damage it? (other than the fact that it is surely causing wear & tear of chassis fan (& other electronic components, which i can't detect, if so) & more electricity bill).....Saying so, i would like to inform that i detected this after about 20 hrs which includes hour of PC being turned off (when that Current/voltage was kind of reverse flowing). PC remains fine till date.

couple more 3)What can be at fault here for allowing current to flow backward, if so? A)Repeater cable cum hub B) Power adapter.........I just added picture of Setup too in 1st post.Thanks

Overpower meaning higher voltage than expected. In the event of (for instance) a short in a device.

@OmnipotentEntity A short circuit by itself does not change the voltage. It might however lead to a higher current than designed for, depending on some other things.

While USB ports in specific are designed to accept 5V power, because power is leaking from the USB Hub i have concerns about the quality of the hub, and whether or not it may short seriously in the future. It should be noted that it already should absolutely not be doing what it's doing right now. Which means that you're probably already exceeding the capacity of the hub, which increases the chance of a power related failure situation.
