"Hub Overload" Connected camera to usb cable, get message from computer "hub overload" all 3 of computers. Replaced cord no help. Other camera (different make) no problem. I have had this camera for a while no problems.

Sir/Madam

1. Is the printer turned on?
Make sure the printer is turned on.
Make sure the power cord is securely plugged into the electrical outlet.
Test the power by plugging in the power cord of another electrical appliance to an electrical outlet and turn it on. If the power to the other electrical appliance comes on, the printer may be considered to be faulty.

If this product is not recognized:
Proceed to the next step.
2. Are your computer and the printer correctly connected?
Make sure the USB cable is securely connected to the printer and to your computer and check that the USB cable is not damaged nor badly crimped.
The printer will not be recognized during the driver installation if connected to a printer switch or the printer buffer. If this is the case, try to directly connect the printer to your computer using the USB cable.
If you are connecting the printer to your computer via a USB hub, connect the printer to the first-tier hub from your computer. If the printer driver is still not recognized on your computer, try to directly connect the printer to your computer without the USB hub.
If you are connecting the printer to your computer via a USB hub, make sure the USB hub device is recognized by your computer.
If this product is recognized:
Close this page to return to the installation window.
If this product is not recognized:
Proceed to the next step.
3. Does your computer provide USB or IEEE 1394 support?

It's a USB hub, it doesn't require any special drivers. Just plug it into the computer and plug in devices. Be aware hubs have very limited suppliable power so if you plug in a lot of devices that use a lot of power and have no power supply of their own you will overload the hub and it will stop functioning.
If the computer is having problems identifying the hub. Go into Device manager and locate any yellow ? or ! devices right click the device, properties and post the status codes.

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.

You might want to consider NOT connecting your camera to your computer.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program.

The two devices are probably overloading the USB power. The total power output on one hub in the computer is limited to 500mA. If they work separately, this is most likely the problem. The way to fix this is to purchase an inexpensive powered USB hub (it will have a power supply to plug into the hub as well as the USB cable to the computer).

Believe it or not, this problem is actually related to the computer, not the printer.

I can tell by the error message that you are plugged into a USB hub. Unplug it from the hub, then plug it directly into your computer's back USB ports, not the front ones. It will probably work now.

To properly fix the issue, you need to purchase a powered USB hub.

Essentially this happens because the printer is power hungry. Passive USB hubs like the one you have can only provide enough juice that your computer gives it. Since your computer doesn't want to fry out by "overloading" the voltage on the line, it reduces the power and throws that error message.

Now, if you are getting this message on a laptop computer OR you plugged the printer into the back ports and the unit STILL does not work, the printer or USB cable has a short and needs to be replaced.

Good luck. Please rate my response or post a comment on your original question to allow me to further assist you.

Do you have many other items plugged into additional USB ports? You can "overload"power on a USB hub, i would try to leave your memory stick plugeed in, and restart your computer to see what happens. That or unplug other USB devices that may be in use such as scanner, printer, camera, etc. and try it with those unplugged. A longterm solution if this works is to pick up a powered usb hub, you can pick one up online for around 15-20 bucks.

You can plug a USB hub into the working USB port on the computer. The USB hub can have several ports so you can plug in several USB devices.
I suggest you get a powered USB hub because if all the devices that you plug into this hub exceeds 500mA then your computer's USB port will stop working because it could not supply enough current.
You will not need to plug in the power adapter into the hub if the device/s do not overload the computer's USB port.

Hi, are you using a USB hub or attaching directly to the computer USB port?

1. If you are using a USB hub, which is then connected to your computer ... you either need to
1. Plug the camera directly in to the computer so that the computer supplies the USB with more power to the camera.
   
2. If the USB hub has a power plug/adapter, use it so the USB hub gets more power to handle the task.
   
3. Buy a different USB hub that has a power adapter so enough juice can be supplied to the tasks that USB is asking to do.
2. Some USBs on the computer aren't giving enough power, you may have a bad USB port, try another one.
3. Use a Card Reader, which is much faster to download pictures than from the camera.
   

Reason: some times, the USB task is asking for a lot more power than is being supplied through the current USB path. You have to either add power through an adapter or plug directly in to a power source (like the computer directly, or a reader that doesn't require as much power to operate it).

This should help, if so, please mark as FixYa!

ThankYa!

a simple solution is buy a powered usb hub ( which has an adapter which plugs into the mains) that should solve your problem
