I wanto to use this to power other USB devices - but it automatically turns off after about 20 seconds. How do I prevent this?

It's shouldn't turn off unless the device that you have it connected to is already fully charged then it will shut off by itself. I would try emailing them for support at tony@oxausa.com

There is no 'switch' to turn on the USB. Plug the cable into your device and it charges. I do not know if there is an 'internal switch' of if power is always available. However, in regular plugs the power is always available and only when the appliance is turned on and the circuit is completed is power used. I also do not know if the 120 to 5v converter is using power even when the USB is not being used. Electricians?

It may be that your devices connected are drawing more power then the hub can handle. That happened to me when I plugged in more than five devices. I have ten things to power/data transfer, but I have to use two of these 10 port hubs. After about 2.5 amps (12.5 watts) of total draw, the hub is not reliable. Hope this helps.

I've had the same experience. The quality varies greatly from unit to unit and the USB connection is a big problem and is usually the first thing to quit working. My advice is, if you like the 1129 return it for one that is fully functional. Otherwise ask for a refund. Keep in mind that the average functioning lifespan on these units (I've had more than a few) is limited to months, not years.

Do you have other devices using the other ports at the same time? There is only so much power that the USB port can pull from a single USB 2.0 and 3.0 at a time.

I have never used it like that myself as my backup drives do not use the usb as a power source. I suppose you could use it that way as long as you use the hubs line power source. Most of the time I do not use the hub's power source as I use it as a conduit from my laptop's usb.

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.

the usb port is for outgoing power, and as long as u have ur own cable, it'll power just like any other USB. very versatile device for 20$. =)

I just tried it. I put my computer in sleep mode and all the devices that are plugged into the controlled slot turned off. So if your peripherals are plugged into the the controlled slots they will turn off.

To the best of my knowledge, powered USB riser will not work without being powered. Although I have not tested it myself.

I don't think so. I use the anker to power a pair of USB speakers and it does not shut off at all.

Hi M. Prince,Just like the listing note stated, we recommend that you avoid simultaneously connecting five or more of such "self-powered" devices. To ensure a stable connection, the connected devices must not exceed a combined current of 5A. This is especially important for any devices with high power requirements such as "self-powered" hard drives which draw power from the USB port.

I am in agreement with Thomas. I have been fortunate I guess, mine comes on every time. I would verify your power connection and cable to ensure it is not faulty. The power input is just a mini-usb which can be an easy and cheap replacement.

It works with mine. What I am experiencing is that when it is plugged in I get "unplug a USB device" message that disappears when any of the plugged in items is unplugged.

UPS as in universal power supply? The device is set to power itself off after 30sec or so of no data transfers, seemes to me like you might have a problem with usb on your computer mine worked flawless out of the box, make sure yours is not set to esata mode one front button jumps between usb and esata so if its left in esata it will turn off it you dont have esata

Try different chargers. If it is all the way exhausted, plug it in and wait 20 minutes or so. Sometimes it doesn't respond for a while, until it has a little bit of charge. Good luck.
