A powered hub should provide the USB standard power to each of its ports. That will be 500mA (for 2.5W per port) for USB 2.0, or 900mA (for 4.5W per port for USB 3.0). The rating of the hub should match the total power of the ports (the number of ports will drive the hub's power, so you can't go by just the total power figure). Multiple thumb drives ...

The answer depends on two factors: What is the power capability of ports on your hub. Some hubs have built-in power switches with certain pre-set limits (which are subject to manufacturing variations), some have no control or protection other that "resettable polyfuses" that may have marginal threshold. You can do some experiments with your hub by ...

A little confused on exactly what you are asking, since your title and question seem to be two different questions, but here goes.... For your title question "Would a 3.0 WD My passport HD overpower a powered 2.0 hub" --> I have never seen any USB 2.0 port that could not power a USB 3.0 device. The only difference would be since it is a USB 2.0 port you ...

People say different things about charging currents on mobile phones because the charge depends on particular phone charging hardware, its battery capacity, and firmware that controls all this process. And every phone is designed by different design team, and can behave differently. It depends if the phone supports so-called USB "Battery Charging" (BC) ...

Thing is in most cases it won't matter, usb 3.0 or 2.0, they will both work. But problems may occur. For example when I tried to unlock bootloader on my HTC One M7, I didn't work with usb 3.0 port, it had to be 2.0. So yes, in 99,5% it really won't matter, but if you might operate with some a bit older devices on software level, you might want to get at ...

It'll just work. USB 2.0 devices or lower should work perfectly on USB 3.0. USB 3.0 devices will work slower on USB 2.0. The USB 3.0 socket has some extra pins that are just not connected with a USB 2.0 plug USB 2.0 and 3.0 motherboard headers are completely different and you can't use a USB 2.0 front panel on a USB 3.0 motherboard header and vice versa. ...

On Dual-Boot between Windows 10 and Windows 7 (pro for both), the xHCI controller bypasses the legacy usb ports (loads no legacy usb ports). Setting xHCI to disabled allows the dual boot to function correctly under ASUS bios using EHCI controller.
