Will it receive sufficient power from usb 2.0 port?

The light comes one but drive will not show up in the bios or device manager.

Well I've never mounted this type of drive into and external enclosure but I'm fairly certain (about 85%) that you'll need more power than what a USB 2.0 can supply. Then again, I could be wrong.

Yes, it should. Just pay attention that you use the correct port (marked "2.1")

Yes it will work fine, but of course only at USB 2.0 speeds.You can also use the USB 3.0 cable it comes with to plug into a USB 2.0 port.

No! A USB 2.0 port supplies only 500 milliamps of current at 5 volts. The closest notebook hard drive on the pile on my desk has a label stating that it requires 700 milliamps. This adapter will work much of the time, but when the drive needs a burst of current (as when spinning up the drive and moving the armature), the voltage will drop and you'll get an error. This is why USB 2.0 adapters for hard drives always come with their own power supplies.

Thanks to you all for your response. I guess I will have to live with USB 2.0 speed

Every port I have used (2.0 or 3.0) provides sufficient power for the unit.

Yes it will. I only use it on a 2.0 USB port on my lap top. In fact, I am using it on a 2.0 USB hub that is plugged into my 2.0 USB port. I have had no problems at all using it this way. Works well.

Yes it will work with USB 2.0 plugs. I used this on my pc desktop 2.0 USB plugs and it works fine.

Depending on what you put inside it, you might need USB 3.0USB 3.0 can supply much more power than USB 3.0And now there is even USB 3.1

You need to check your notebook cooler to see if it supports the voltage. I doubt it though. USB2 supplies 5V DC and 500mA. If your cooler shows a higher rating than that: don't try it. You'll break the cooler.

No it will not. Power is less than 1A for both ports. I ended up returning for a refund.

Yes, you can use it in a 2.0 USB port. It will not be as fast as the USB 3.0 port but it will work fine.

Sorry, I do not know, I could actually never fully install this because I don't have available power on the power harness, at least with the correct connection. I am disappointed that without power this doesn't even seem to work for usb1 and usb2 as it should. This was a disappointment.

No and yes (it charges/runs devices off of the bus at that point). Keep in mind with no supplemental power you will be limited by whatever the USB bus can provide on it's own (5v, 500mA for 2.0 and 900mA for 3.0 bus)

I just confirmed that the Plugable USB 2.0.4 will power an RPi unit directly. The RPi only draws 5W, so it's safe.

The 2.0 port is powered through the 3.0 header. It is divided up in the unit itself. When you hook up the 3.0, the 2.0 will work as well!
