Is the power entering through the USB entrance? Or can you only take power from the USB port?

The USB port is powered by plugging into a wall outlet. It then charges your devices (phones, tablets, etc.) through the USB port into a cord into your device. I am not sure if I understand your question completely, but you can not supply power back through the USB when it it is not plugged into a wall outlet (I don't know why you would want to do that. What would you be sending the power over the USB to? A power outlet??? Also, there is only one USB outlet on the device so you can not charge from say a laptop to a phone. And again why would you, just hook the USB cord from the laptop directly to the phone in that case.)

It is powered by usb through your computer. No other power supply is needed.

It plugs into the USB port of any computer. There is no further power required.

No it has three built in outputs (the button to switch one input to the other and then the two USB outs to the computers) on the front there is a DC input, but mine is not pulled into a power source and has been working fine for the last year.

To power it through the wall you have to buy the USB plug, that's how I power it, I haven't even hooked it up to my laptop yet.

There is no USB power input on this unit. Power is supplied and the internal battery charged by the supplies power supply/plug. If your USB Battery had the appropriate plug adapter, I could see that working though. Hope this helps.

This doesn't work. No any power on when I inserted USB into computer. Can I return it for replacement?

Some laptops do not apply full power to the USB ports, if it runs on one your computer supplies full power and you do not need the extra plug.

Sorry I never hooked up the internal USB port on this card. If the out side ports work then most likely the internal port is bad. If the external enclosure gets its power from the USB port and it will work on the out side port I would say its bad. Did you try some other USB device on the internal port? If it worked but will not work with the external enclosure then it means it does not have the right connection to supply power to the enclosure.

I use a powered usb hub. So I can plug many things into the hub and it has it's own power pack. Then I don't overload the onboard power from the pc.

Yes. That's the main purpose of the mini USB, for power pass through. Hope this helps.

No, there doesn't appear to be a way to open it. However, at that point you could probably just power it through the USB cable.

I can plug it directly into a USB port but just to provide power I believe you still need to use the SD card

USB is for firmware updates which I have not tried. Power is only through the 4pin Xlr connector.

Are you using the proper power supply. I was cleaning rearranging my desktop, and inadvertently plugged the power supply from my modem into the laCie drive. It had enough power to turn the light on, but not enough to actually run the drive. I HAVE had a couple issues with my drive. The USB port now routinely disconnects for not apparent reason. Makes it difficult to copy large files.

yes it needs a power input .....but it basically plugs into the mother board pci slot..

It has a separate power supply, unfortunately it is not USB-powered.Hope this helps & enjoy.
