If you see something wrong with the device everytime you plug in something to the USB hub doesn't necessarily mean that the hub is defective but it may actually mean that the device may not be receiving enough power to make it work. As we all know USB a device that may or may not have its own power but at least we know its working when by check the light indicator on the device or checking in device manager and that is an indication that it may or may not work with a hub and may need to be directly connected. If device you hook up is working with direct connection try isolating it by hooking it up from one port on the hub to the other this may actually help you out determining if there is defective port on the hub otherwise you got a lemon any may to return the product as well consult with them which product have they tested that actually worked with it.

When i put the USB cable and connect to the LAP, its not getting charged. How can i solve the problem? do i need to install any software?


Hi - when you say "LAP" I assume you mean laptop or notebook computer. Some computer USB ports do not have sufficient power to charge (or operate) devices like cellphones, GPS, large external hard drives, etc. You may be able to charge if you disconnect all other USB devices that aren't needed to run the computer. In order to get around the problem without having to do all that, either purchase an external charger for the GPS (which may be fairly expensive) or purchase a powered USB hub.

An external powered USB hub looks like a traditional USB hub, except for the fact that it has a power cord to connect to your home power outlets. The power cord will often look like AC adapter. The powered USB hub is ideal because they provide additional USB ports, are fairly inexpensive, they provide all the power for the USB devices that are connect to them (the computer's internal power supply is not used) and it can power or charge devices connected to them without needed the computer to be powered on. Simply plug the USB hub into a USB port, and AC power source - then connect the devices that need a large amount of power to the hub's USB ports instead of the computer's USB ports.

The parts included with powered USB hub (clockwise from left): USB hub, USB connecting cable and AC power adapter.

Many powered hubs will work without the power adapter - however they will supply power to the devices connected from the computer's internal power supply.

I hope this helps and good luck! Please rate my reply. Thank you.

My computer does not show that the USB is there. Nothing comes up when I insert the USB in the Hub


Hi, if you're plugging a USB device into an external USB hub, make sure that the hub is externally powered. Most of them need to be and come with a AC adapter that you need to plug into the wall.

My Targus keeps disconnecting what is connected to it then will reconnect (seems random) anyone else having problems with disconnecting devices plugged into the hub? Model ACH7405US


This USB hub is not powered by an AC adapter. Therefore, some devices that need more power will not work well on it. You don't mention what it is you are pluggin into it, but I suspect this may be your problem. Devices like webcams pull way too much to be on a hub without AC.

Did I solve your problem? If so, please rate this. ty.

What is this small round hole for???


Although i have not seen your device specifically i looked it up and that unit if I am not mistaken has an option to plug a switching power adapter on it IF and only IF in case you might need it to power on additional devices. Some USB devices need more power than normal hence the adapter but any device that runs on its own power and small USB devices dont need such power then you do not need the external adapter ( Sold separately and not by the same company) Basically you are not missing anything dont worry if the unit works as it should then you are ok.

If you need further assistance just message me.

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)

My computor switches off the moment i plug in the wd passport.


Probably a power issue. Your new computer has less extra power capacity and the external drive is pulling from the USB port power.

What you need is a USB hub with an AC adapter that powers the hub and any devices that are connected to it from the external AC power adapter and NOT from the USB bus. In other words look for an external power adapter that plugs into the wall as well as into the USB port. Don't get a recharger for an iPOD as that will not do you any good. And don't get a hub that says "powered" or "external power" that does not have an AC power adapter because it is still sucking power off of the USB port.

Try shopping for a D-Link DUB-H4 High Speed USB 2.0 4-Port Hub. It is a good choice if you are not going to plug any USB 1.1 devices into it. Read the reviews for any device you choose.

WE CHARGE THE MAGELLAN GPS AND TURN IT OFF. BUT WHEN WE GO TO USE IT AGAIN IT IS DEAD. I ONLY HAVE THE LIGHTER OUTLET TO HOOK UP FOR POWER SO WHEN I NEED TO PROGRAM IT IN THE HOUSE I DO NOT HAVE A WAY TO...


Hello kdiltzbook,

Most GPS units can be charged three different ways:

1. Connection to a computer via USB port
2. Connection to a automobile via cigarette lighter plug
3. Connection to a wall outlet via an AC adapter

Typically most GPS devices these days include only the USB cord. Some GPS units also include the cigarette lighter plug. For most GPS units the cigarette lighter plug and AC adapter are optional accessories have to be purchased in addition to the GPS.

You don't mention which model of Magellan GPS you have so I am not sure which cords your GPS should have included. It sounds like you have the cigarette lighter cord and the USB cord? I am sure that Magellan has an AC adapter available for your GPS. You will want to contact them directly (their website is http://www.magellangps.com) or visit an electronics store that sells Magellan GPS receivers (such as Best Buy™) to purchase the adapter.

However, most GPS receivers can be charged from the USB programming cord on the computer. However, ensure you are plugging the cord directly into a USB 2.0 on the computer itself NOT a port on a USB hub. (A USB hub may not output enough power to actually power and charge the GPS.)

You will also want to check and replace the fuse on the automobile plug.

I believe that both the USB and automobile cords should be charging the GPS. If neither adapter is charging the unit then the problem may be the GPS unit itself. The GPS may have a bad battery or problem with its charge circuitry. If that’s the case the unit may require factory service as the battery pack is generally not considered to be end user replaceable.


Best Regards,
Ken

S75 & Mem Stick Reader Help


I had the same concern a month ago when I bought my USB Stick reader. As you mentioned, the manual says there is no guarantee... I don't have a USB hub but I do use the USB port that I connect the USB Stick reader for other things. No problem. In fact I did not even have to use the supplied CD that came with the reader to install the driver for it. As soon as I pluged the reader to the USB port. Windows ME (yes I'm running WindowsME) found the device and install the built-in driver itself. Why don't you just wait until you get your camera and try it out first. Good luck.
