SOURCE: Power supply for Targus 4 hub usb 2

Most USB hubs do not need an external power supply, except when a connected USB device draws more power than the computer/laptop USB port can supply. In this case an external power supply will need to be connected to the USB hub.
Normally this would be a 5 volt power supply, but make sure the polarity on the connector matches the power connector on the hub, check the label on the hub, sometimes it states to power requirements of the hub as well as the polarity on the connector. Normally the pin on the hub's power connector is positive (ie. +5V)

SOURCE: Targus Travel USB 2.0 4-port Hub

Some external USB hard drives, typically 3.5" drives, draw more power than a singlee USB port can provide through one port (the standard is max 5v, 500mA per port). Usually the drive will ship with a USB cable with 2 USB male connectors on one end, with one colored red. This is for you to plug into a second USB port to draw up to an additional 500mA power through the cable to help spin up your external hard drive.

Most USB hubs I have seen draw a maximum of 2A or less and the allow this to be drawn upon by the ports at up to 500mA per port. But a 7-port hub will not be able to provide full power to more than 4 ports, which is normally OK because few devices pull the full 500mA. Sometimes just reducing the number of items on that USB hub to 3 or 4 will solve your issue. And you cal also use a hub with its own power source to help meet the current demand for all 7 ports.

All I want is support of a 4 port usb hub. What is the voltage and amps of the power supply. Don't you support it any more.


The Standard voltage for USB is 5V and a USB 2.0 port on your computer will give you 1A.
I checked on eBay, a good source of information on what is available and several 4 port powered USB hubs are rated at 0.5A per port.
The ones that quote specifications on their power supplies say 5V 2A.

There is little support for them as there is very little in them that can go wrong, and if they are fail, it is simpler to replace them. One i saw while looking was under $15, shipped world wide.

Where can I find a power supply for the Encore ENU-4USB 4-port external mimi USB hub?


The power supply is a 5 VDC, 500 mA (outer negative, inner positive) commonly used for mp3 players, but probably you must cut the mini usb plug and adapt a compatible jack with the hub.

4 port HUB is connected. My computer doesn't show it. Help! It is all plugged in with USB cable and when I go to MY COMPUTER it doesn't show.


The hubs usually show up in the hardware list and not as a seperate device. Only way to know it is there is to plug a usb device into it.

I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems similar steps may be adapted to suit.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability

2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)

3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.

4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.

5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especialy true if you move a HUB to another port

If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further

USB port malfunction


CHECK THE RATING ON YOUR POWER SUPPLY BECAUSE SOME LAPTOPS WILL REGISTER THE POWER CONNECTION PORT AS A USB PORT AND IF YOUR POWER SUPPLY VOLTAGE IS TO HIGH FOR THE COMPUTER IT WILL REGISTER IT AS SUCH, "HUB-PORT" IS SHORT FOR MAINBOARD PORT ON SOME DELLS. UNPLUG YOUR POWER SUPPLY AND CHECK THE RATING ON IT COMPARED TO THE DELLS INPUT VOLTAGE, THE INFORMATION IS NEXT TO YOUR SERIAL NUMBERS AND LABELS ON BOTH PEICES KEEP ME POSTED... JON-T
