why the usb cable does not get power from computer connection

In the case of the usb you are able to add some storage space. I infact have a Sunpak 72 in 1 high-speed car readers. I got a cord USB to a small 5 pin. This will allow you to transfer data too and from the tablet. By using this feature it allows the tablet owner to install some apps without consuming large amounts of internal space.

yes. Also restarting, or pulling electric plug and re-plugging again helps also. Try changing your power adapter. It may help.also always plug in usb first than power. I dont know why but this help too

USB Cable connects in the back and the other end can be connected to a computer USB Port or to a USB electrical adapter that plugs into the wall for power. You will need to purchase these seperately.Kirk B. answered on December 29, 2013

Single USB connection. It does not draw power from the computer. It has a plug for external power. I don't like the external drives that draw their power from the computer.

It might be that the drive you put in is bad, it's not turned on, or your USB port is not providing it enough power. I ran into the power issue with another drive due to my computer being a macbook, solved by getting a usb cable with two plugs - one for power, one for data.

It's powered from the computer's usb port. It has two usb cord connections, one of which must be plugged into a powered usb port on your computer. Check that your computer has at bleast one powered usb port. Most likely it has several.

I don't know for certain if the computer connection is cut off. I do know the power is cut off which in most cases would cause what you have connected to not function. I often use the hub in conjunction with a couple of led lamps as makeshift desk lamp when travelling.

Be sure you have the laptop battery removed when connecting the cable also do not have the laptop plugged in when installing.

Are you sure that you used the USB cable correctly? You need to plug both USB cables to your computer for the drive to work. One would only provide power, and the other would be used to transfer DATA, neither one can work on its own. As a troubleshooting step, try to use a drive in the enclosure that you know for sure is not dead, if that one works, and the other one is still giving you problems, then it might be a problem in the drive itself but not the enclosure. However, if the drive that you know is working well, still doesn't show up on the computer, then it might be a problem in the enclosure. Hope this helps!

Unplug and replug the cable into the hard drive and the computer. There are many tiny connectors, and sometimes if the plug is even a little crooked it won't work. If that doesn't work, try it with another hard drive, to see if it's the adapter, or your drive. Also, if you are trying to use only one USB plug, use the one in the middle of the cord. The plug on the end is just for extra power (in case a single USB port doesn't have enough juice to power up the drive; I've never had to use it).

Most likely has to do with settings for USB inside Advanced Power Settings that you can change starting inside Control Panel--Power Settings--Advanced Power Settings

1) are you sure your cable is a USB 2.0 piece? 2) is your cable plugged into a direct port on the computer and not a hub, especially if the hub is un-powered

If you are using the USB3 port, I am not surprised. If you are using Windows, the power saving suspend mode needs to be disabled. This may be what is causing the shut down.

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.

Yes, you use the USB cable for setup on your computer, after that it's just used for power

Turn it on , Use the cable sent within the box , plug the USB to your computer and the other end into the line in/5v slot .This worked for me ,

It does not provide power to any device. It is powered but does not provide power (other than through the USB ports)
