If your system is displaying code 10 or "the device cannot start" error messages, resolve the problem with a little troubleshooting.
These messages arise when your computer does not recognize universal serial bus (USB) devices.
Faulty USB devices or malfunctioning drivers are common causes of a unrecognized USB device. It is important to detect and repair the underlying issue to prevent serious harm to your personal computer.

Plug the USB device into another computer.
If the alternate computer displays the code 10 error, there is a problem with the USB device.
Return the device or purchase another one.
Plug the new device into your system. Make sure the code 10 error does not appear.
Click "Start" and right-click "Computer."
Select "Manage" and click "Continue" if the "User Account Control Prompt" appears. Open "Device Manager."
Select the faulty USB device.
Notice a yellow exclamation warning next to it.


Right-click the faulty USB device driver and select "Update Driver Software."
Allow the driver to update.

Right-click the faulty USB device driver and click "Uninstall."
Exit the Device Manager.
Restart the computer.
Allow Windows to reinstall the driver automatically.
Ensure that the USB device is working correctly.
If you computer came with a motherboard disk the drivers should be on it.

it might take some time being a freeware driver solution
Note: it will find all of your outdated drivers

This will automatically search for and find the correct driver you will have to update every driver individually once you update you might be asked whether you want to restart or make a system restore point.

Click no to both of these then continue updating each driver free then restart once all of the drivers have been updated.

I have the same problem, my Sahara Notebook Image book's usb ports are all not recognizing any usb device i have tried to reistall the os but nothing happening, so what can i do coz the recovery disk was lost.

Refresh and reinstall USB Ports Of Your Computer Hello there, the other day i tried refreshing and reinstalling the USB ports on my PC, as some of my connecting devices are not recognized. I present the detailed procedure on refreshing the USB ports.
Let’s go!!

Here are the steps to refresh/reinstall/uninstalling the USB ports on the computer.

The USB port needs to be refreshed to make sure that no other device has captured the USB port of the computer. The Mouse, video camera, your external USB hard disk; what ever it may be.

Follow the steps given below to refresh USB ports.

1. Right-click My Computer icon on the desktop, and then select Properties.
2. Click the Hardware tab.
3. Click the Device Manager Button.
4. Click the plus (+) sign to the left of Universal Serial Bus controllers.
5. Right-click the device listed under Universal Serial Bus controller and select Uninstall.
6. Click OK to confirm the removal of the device.

Please note, repeat Steps 5 and 6 until all the devices under Universal Serial Bus Controller are removed.

7. Shut down the computer.

CAUTION: Ensure that the Shut Down option is selected, instead of the Restart option.

8. Wait for 5 seconds and then restart the computer. When the computer restarts, a "Windows has detected new or added hardware" message window will open.

The above steps will refresh the USB ports.

Now connect the USB devices like mouse, video camera, your external USB hard disk...USB hubs...whatever you like and the drivers should install automatically.

Tip: It is always recommended to connect the main USB devices at the rear end USB port. As they require more power to initiate.

The above steps are for XP operating system. When coming to the matter of Vista, please note the changes below:
===========================
1) Right-click Computer icon from the desktop , and then click Properties to open the System Properties window, and then select the Device Manager tab.

2) Click the Plus (+) sign next to Universal Serial Bus Controllers/Root hub.

3) Click the USB Composite Device entry to highlight it, and then click Remove. If a screen appears to confirm the deletion, confirm the deletion.

4) Disconnect the USB cable to the all-in-one, wait a couple seconds, and then reconnect the cable. This should restart Windows device detection (Plug and Play).

5) A New Hardware found screen may appear, click next through all of the screens that appear for the Wizard to install the USB Composite Device. Click Finish once the wizard completes.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

This solution worked for me when I got the USB device not recognized message:

It can be quite frustrating. I've heard that older computers are more likely to have the USB device not recognized message.

Re-install your USB driver and Chipset Utility

uninstall driver then turn off the PC then unplug the power cord from power socket, short its legs then leave it unconnected for 5min, then reconnect it to power socket and turn on PC and install driver it should work :)

Try to plug in the usb device in the pport which is at the back of your system. This should work. If not then revert back. 
Thanks

We can fix it -- and recover the data (provided it is recoverable -- which it generally is). If we don't get your data back, we ship the drive back to you and you pay nothing. We've been recovering data for over 16 years and are successful about 85% of the time.
