whenever i connect external hard drive or pen drives to my laptop ,at first it detects and installs the software correctly,but after i remove it and reenter it it does not shows any usb device.

on opening the device manager the usb device with name "usb root access" shows yellow icon with some sort of error.

 

after uninstaliing the driver an restarting the laptop it again works nicely but again the same problem.

Possible that your USB chipset is bad, and you need to send the unit off to HP for Motherboard replacement.  What is showing up in Administrative tools > Event Viewer?  If you want to spend $50, you can get the Passmark USB loopback tester and software, but really not worth it in my view.

Open the Device Manager and scroll down to the Universal Serial Bus Controllers, since there is a yellow warning icon the tree should already be expanded.  If it is not click on the diamond to the left of the USB icon to expand the tree.  Place the pointer on the item with the yellow warning icon and double click on it.  You should see a image similar to the one below, but yours should have the yellow warning icon.
