When I plug in my camera or ipod nothing happens

I go to the device manager and the system controlers and the root hubs all show that they are working properly but they do not show that I have plugged in anything.

    if you have any working device connected to the system try to connect the ipod or the camera in that port and see if that gets detected ... if no than try install the drivers again with the motherboard cd and if that doesnt work try to reload windows and if still that doesnt work last option is to update the firmware of the motherboard that is the bios ... but you need to be carefull about tha... one mistake and you loose the motherboard and than follow the instrucctions on the readme file which you will get with the firmware if that doesnt work that means mortherboard gone bad you can add pci cards which will have usb ports ... or you can change the motherboard

I have sahara n1356 laptop which freezes mouse and keyboard when i start it. what could be a problem


Try following tips:
Try to connect your keyboard and mouse directly to your laptop's USB ports (instead of using the USB hub) and see if they still freeze.
OR
It sounds like you're using an unpowered hub, which in my experience tends to cause most common errors with USB peripherals. It's definitely not recommended to connect any USB devices which aren't supplied with a power adapter (for instance some 2.5" external HDs and those small photo printers). These sort of devices should be connected directly to your laptop at all times.
You could also consider buying a powered hub, i.e. an USB hub which draws its power from a separate power adapter (and not your single laptop USB port).

if it doesn't work you can try this..

Click Start, and type device manager in the Start Search box.
Click Device Manager in the Programs list.
If you are prompted for an administrator password or confirmation, type your password or click Continue.
In the Device Manager dialog box, expand Universal Serial Bus controllers.
Right-click USB Root Hub and then click Properties.
In the USB Root Hub Properties dialog box, click the Power Management tab.
Remove the check from the Allow the computer to turn off this device to save power check box. Repeat steps 1 through 4 for each USB Root Hub listed in the Device Manager.

Under Power settings, check the 'USB settings' -> 'USB selective suspend settings' and make sure it is disabled.
Check Thumbnail, highlighted: Open Device manager, Double click on Universal Serial Bus controller at the bottom, Double Click USB Root Hub, Click Power Management on top right, Uncheck Allow Power...
Hope it works for you.

My usb ports are not recognizing any devices such as my iphone, ipod, etc. I have a dell dimension 4700 runnning win xp sp3


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;

HKEY_LOCAL_Machine\SYSTEM\CurrentControlSet\Services\Usb

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.

Dx2400 with xppro, usb devices doesn't work


I don't think it would be the power supply as the motherboard regulates the voltage to the USB rail.

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. You can update these by downloading them from your motherboard manufacturers' support website.

Front usbs not working(suddenly)


Possibilities:
1) One of your USB devices have faulted, or is causing a resource conflict (or similar)
-- Remove all USB devices, and reboot.
2) Your USB chip/ports have been damaged.
-- Find a spare HardDisk or bacjup your data and re-install Windows and see how that goes.
3) Your Power Supply Unit (PSU) isnt supplying enough power to your PC (usually caused by a Video card upgrade). Try a more powerful PSU ... 400watts should do the trick
4) Bad memory (RAM) can cause wierd problems. run memtest for an hour to make sure your memory is ok
