Since you have these many problems with your laptop, Firstly try to reformat the system and reinstall all the neccessary drivers. Many times reformatting works well as your OS might malfunction when you have virus or malwares in your laptop.
OTHER SOLUTIONS a. for USB:

Expand Universal Serial Bus controllers.
Right-click a USB Root Hub in the list, and then click Properties. The USB Root Hub Properties dialog box is displayed.
Click the Power Management tab.
Click to clear the Allow the computer to turn off this device to save power check box, and then click OK.
Repeat steps 3 through 6 for each USB Root Hub in the list.
On the Action menu, click Scan for hardware changes.
Windows XP recognizes the new device.
Close the Device Manager window.
b. SD CARD Your 1GB kingston card might have virus. use a card reader and reformat the card for future use.
c. Uninstall and reinstall the driver of your finger scanner.

Usually usb device not recognized is due to damaged usb cable or usb port..use a different usb cable and connect it to your pc, if your usb cable is ok then connect it to a different usb port. if the problem in not with the usb cable or port install driver from the cd you got with camera. if you dont have that cd download driver from the device manufacturer site.
In most cases this message is fairly true and accurate. Whatever it is that you plugged in is most likely broken. Two things you can try to test this:
1. Plug it into another USB port in your computer, if it is the same message, move to step 2. If it works, then there may be something wrong with that USB port on the computer.
2. Try the device on another computer. If you get the same message, the device is probably broken. If it works, then most likely there is something wrong with the USB ports on your computer.
Let me know if you need more assistance.
You have to do some steps about fixing this problem :
1: Go to Device manager by right click on my computer then manage and then device manager.
2: Go to universal serial bus controller and export it.
3: in each USB root hub right click and then properties.
4: In properties screen select power management tab and unmark on " allow the computer to turn off this device to save power ".
5: After finishing this steps in each USB root hun restart your computer and then done
Did this suddenly start to occur? Were they working before? If so, it is very simple - shut down computer, remove the battery and unplug any power source, wait a couple of minutes and reassemble and power up. Wala! I read all kinds of complicated instructions, started with the simple, and problem solved.
try consulting the mfg for updated drivers. Try removing the usb port it's using and letting it redetect the port, also see if there is special software that comes with the usb camera and reinstall that. If all fails reinstall windows.
Device manager shows the USB port if they are attached to you notebook. And in your case they are attached.
So it will show it.
Now in your case the problem is in your USB.
Get it changed. If it is in warranty peroid then dont u take any risk. Let it be replaced. Or give your notebook in warranty period to the company from which you bought.
