Is it better to plug the dragonfly into a USB2 port or is it ok to plug into a USB3 port?

There won't be any performance advantage with USB3 port because data transfer to Dragonfly is well below maximum transfer rate for USB2. If you have any USB3 devices, such as external hard drive, you might as well reserve that port for them because they can use much higher transfer rate and data is simultaneously bi-directional.

Depends on the computer/laptop a lot of manufactures like to make the connection blue, or have a special symbol. If you look in your computer management->Universal Serial Bus controller you should see one listed as USB 3.0.

I have USB 3 version (backward compatible with USB 2) and the power supply has steady blue light on when it is plugged in.

I plugged the small USB transmitter into an available port on my computer and it was connected. You don't need a driver. I do know it was very simple to connect. No issues whatsoever. It works beautifully.

My USB attach point moves forward and rearward. I found that it is much harder to connect USB3 connections than USB2. I think you will find the design of most docking base will be the same. If you connector moves side to side return it.

short answer, be cautious. a USB 2 port offers a maximum power output of 500ma, USB 3 is 900ma. That means a device that really needs power (like an external HDD) and one that is USB 3 may require and attempt to draw more than a USB 2 port can provide. This mat result in the host port failing or frying and/or the loss of data in transfer and the corruption of existing data. These very nice but simple drives have no optional power supply port so you take the risk, especially on single USB laptop ports.

Yes. USB3 is backward compatible with USB2, and the USB3 cable plugs into a USB2 port in your computer.

Just note that USB 3 ports of this docking station run at 2.5Gbps/sec (not at 5Gbps/sec). This only becomes a limiting factor if you connect an SSD thorough them. For other stuff 2.5Gbps are more than enough.

The 2 usb is there to simply give more power. Mine ran perfectly fine with 1 usb. But if it doesnt just plug 2 usb in for more power

NO, USB 2 only. The only reason USB 3 is mentioned is that it will work in a USB 3 port, but it will be USB 2 speed.

You need to plug both USB ends. This way, your external HDD will draw more power than from a single USB 2.0 port.

If used with the power adapter you get the highest lumen output which is the way I preffer to use it. You can power it off 1 or 2 usb to change the power output. The quality of the signal is the same on USB2 or 3 but the error rate will. Be higher on usb2 if watching fast action movies. I primarily use it for business power points and picture slide shows. There may be a better solution from other vendors if you are looking for a portable movie setup. 200 lumens and above will give you clearer blacks and higher contrast and colors that pop.I am satisfied with this unit for what I use it for.

Yes, it should work fine. As far as I know USB3 is backward compatible just as USB2 was with basic USB. I use my USB3 ports on USB2 devices all the time. Go for it, it's a good hub. I'm still very pleased with mine.

The Goodman plugs into USB 3 or 2. It doesn't matter what motherboard you have. If you have.USB 3 you will get optimum performance.

This one works great with all USB ports. I'm thinking of getting another. Good luck to you.
