The message "power surge on

What is happening here is when the camera is plugged in it is drawing more current then the port can handle. This is likely the cause of a short in the camera and is not something that is easily fixed on your own. If you still have the receipt for the camera from where you bought it take the camera back and exchange it for a new one. Otherwise you can try plugging it into different ports on your computer but the same message is likely to still occur.

When i m connecting my cam , it wil cm : a usb device has exceeded the power limits of its hub port.

You will either need to remove other usb devices, or buy a powered USB hub as your computer cannot provide enough power for all the usb devics connected to it. What else is connected to the usb?
I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.

Webcam installation

When you installed the camera did you use generic Windows drivers? If so, try going to the logitech website and downloading the latest drivers for the web-cam. Unplug the camera before installing the new drivers, it may prompt you to plug in your camera, if not plug it in once the installation is complete. Restart your computer and make sure your plugged in as well if it is a laptop. Another reason for no response could be no power is coming through the USB port, either because the power connection is burnt out (this doesn't mean that powered USB devices don't work in the port) or it reverted to a 1.1 version of USB. This is a common glitch that can usually be fixed by changing USB ports or restarting the computer. Make sure you don't have too many devices being powered only through the USB port. If any USB product also comes with an adapter always use that adapter if possible instead of using the USB to power it. This will ensure a longer life of your ports. If the latest drivers are installed and you know you have a working USB port that provides power then you more than likely have a bum camera. (Electronics generally fail either very early or very late in their life cycle)

My 5v logitech camera will not turn on and i have no idea whats up with it, any assistance would be helpful


Just a suggestion: Windows can disable the USB ports to save power. This setting is in Windows and it does not matter if the computer is a desktop or laptop. You can test to see if this is the cause. Turn the computer completely off, let it sit for 5 seconds or so and then power it back on. If the web camera turns on and works after the reboot, the Operating System is powering the USB ports down and causing the issue.

You can tell Windows to leave the USB port powered on all of the time. Click START, and go to the CONTROL PANEL. Double click the SYSTEM icon, go to the HARDWARE tab and then click the DEVICE MANAGER button.

This brings up a new window that lists all of the hardware that is in your computer. Click the + (plus sign) next to the UNIVERSAL SERIAL BUS CONTROLLERS entry. Scroll down to each USB ROOT HUB entry, right click each entry and click PROPERTIES.

This brings up a new window, click the POWER MANAGEMENT tab. Remove the check mark from the "Allow the computer to turn off this device to save power."

Repeat for all USB ROOT HUB entries, click OK to save your changes.

First you must make sure that the computers USB port is actually finding your camera the best way is to use USBDeview

This software will give you tonnes more info about your USB hubs and ports and can also be set to balloon when it sees a new USB device.

The best function of Nirsoft excellent Freeware standalone application is that you can display disconnected USB devices and remove them if required and try to reinstall the drivers if there are conflicting.

Can't make webcam work on Acer Travelmate 4500

This sounds like a USB issue. Not all USB ports on laptops are created equal (they should be but they are not) some usb ports supply enough voltage and current to run usb items properly and some dont. It is always better to run direct from the computer / laptops ports .

If you cant do this then use a HUB but make sure the HUB HAS IT"S OWN POWER SUPPLY !

Also make sure you always use the same port and swapping them around does not always work for all hardware.

USB Port Unrecognizable

It seems that many people are still getting the 'USB Device not Recognized' problem from time to time. Unfortunately there is no easy fix.

Firstly, it's recommended that you make sure every one of your motherboard drivers are completely up-to-date, but you probably already knew that.

In XP, after a USB port isn't used for a long while the USB driver built into the OS sets the OHCI controller to suspend. When you plug a device back in, it can sometimes fail to 'wake up' properly. This problem was supposedly fixed in SP1 but there is a related registry hack that may still be able to help.

Run regedt32.exe and navigate to;


Create the Usb key if it doesn't already exist. Under this key, create a new DWORD value called DisableSelectiveSuspend and give it a value of 1. Then restart the PC.

A long shot perhaps, but I recall having similar problems with a USB hub built into my Microsoft keyboard and adding this key seemed to solve it. It wouldn't hurt in trying icon_smile.png.

Alternatively, removing all entries relating to USB in Device Manager and all associated USB drivers will force XP into refreshing the USB driver stack.

Begin by unplugging all USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software. Next, boot up into safe mode and go to Device Manager. Once in device manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this order;

1. USB peripheral devices (printers etc.)

2. HID and/or Composite USB (Human Interface Devices) You're using PS/2 input devices so you may not have this entry.

3. USB Root Hub(s)

4. USB Host Controller(s) (Universal or Enhanced Host Controllers)

Then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Proceed to plug your USB devices back in, starting with your powered hub. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in.

Hopefully some of this may be of help, let us know how you get on.
