I will be docking a laptop in my office. Will the hub power on upon USB connection?

Yes, but it is best with this many ports that you have the AC/DC adaptor plugged in as one USB port only has 9.1 volts. The adaptor will allow the appropriate power to go out to other devices such as an external hard drive. You will also need it if you want the USB strip to act as a charger for such things as your phone.

yes I have not had any problems with this hub powering all manor of USB devices.

The power supply plugs into any standard electrical outlet (110-115 V). I have not tried using the hub as a bus-powered device.

I tried hooking up a portable 2.5 2TB hard drive and it had trouble keeping it powered. However, when I attached a USB hub to the smart dock, I was able to plug the hard drive to the hub and it functioned without any problems.

It is a powered hub. The only thing I haven't been able to connect was an Apple SuperDrive.

The hub's charging capabilities are independent of the computer. I have numerous devices charging at the same time via the hub, not through the computer, even though they both are connected.

I'm not the seller, sorry. I'd suggest looking up some installation guides because it can be a little tricky I had to buy a powered USB hub when I got mine.

Yes. The manual clearly states that external power is required at all times. USB 3.0 ports are supposed to provide up to 900 mA, each, so requiring an external power source for hubs is pretty much written in stone. Also, it is worth noting that older computer systems probably do not have USB 3.0 ports built into them. My own laptop is a 2011 ThinkPad, and I had to buy an adapter card to get the support.

No, they are both powered by independent adapters. The docking station does not power the laptop.

I have a USB keyboard, Logitech mouse antenna, a printer , and other USB device connected to the hub. All work fine.

When the hub is on and the computer is off, the attached devices are still being powered. The blue lights are to indicate that the port is in use. You have to manually turn the hub off to cut power to your attached devices.

If I understand you right, yes. The hub is powered and will provide power to any thing plugged into it (optical mouse, keyboard, Thumb drive). The 2 "high" power ports are for fast charging something but does not fast charge if the hub is connected to a PC. They supply the usual USB voltage.

Its here on my desk top right now, thus it is easy to verify your question. NO, the unit immediately went off line and disconnected. Upon application of the power it came back on line. I selected this unit for two reasons:USB 3.0 and the higher current capacity. I have in the past been frustrated with "low cost" hubs that won't charge a phone for example.Hope this helps.Michael

Yes. However it depends on the device you are plugging in. If the device is BUS powered, then you will need this HUB to be plugged in a power source as it will need to send power to the bus powered device (for example flash drives or USB powered Mics) If the device has its own source of power (like a camera or a powered external hard drive) then you do not need to plug the HUB into a power source and can serve as a pass through.

I've been using mine with a USB hub since I got it and haven't had any problems at all.

I just tried mine without the power plugged in, and it worked OK with the track ball that is plugged into it. However, I suspect that any device that requires power from the USB bus (like an self-powered hard drive) would NOT work unless the hub itself is powered.

The hub can be powered by the AC adapter and or USB. I have one and I use it to dj. It is nice because if my computer looses power my controllers stay on because the hub is plugged directly into the wall. Don't get the USB 1.0 version I have it and it is terible. I went back and bought the 3.0 and it works great. I run a USB powered light of it so the on off switches are nice. Hope this helps.
