go to my computer>properties>hardware tab>device manager and go down the list to universal serial bus controllers, click on the '+' sign and see if any on the list have a red cross or yellow exclamation mark next to them, if there is '!' then right click and click update driver, if a 'X' then right click and select enable. If still not working, right click anduninstall all the controllers and then restart notebook and the controllers will be re installed and hopefully should solve the problem, if not then there may be a usb port fault on the motherboard

You will have to reinstall the usb drivers again from http://www.samsungpc.com/products/x05/x05_supporteddrivers/x05_supporteddrivers.htm
SOURCE: usb device not recognize
You mentioned that you uninstalled the unknown device from the Device manager. If you uninstall it then connected your usb flash drive you will see an error again on your device manager. This means that the driver for your usb port is not properly installed.
To install it, visit dell website, look for the model of your machine and locate the driver, download it then install from your machine.

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.

After reading the description, I think you need to try updating BIOS and latest device drivers for USB. Because USB are getting power on that means there would not be any fault to from the motherboard.
So please try updating latest BIOS for your notebook.
If you can provide me the product no for your notebook and the operating system which you are using currently then I can find the one for you.
Otherwise you can also do the same.
Type in the product no. on www.hp.com. Then go to software and driver download page, select the proper OS and search in BIOS ROM pack available for your notebook.
I hope this will help.
