    USB not working and yellow mark on the device manager on Lenovo laptop

    Recently got the Lenovo laptop and everything was worked well without any issue and I have updated the operating system of the laptop from windows 7 to windows XP. I have updated the laptop to windows XP without any issue but after doing this i am not able to find out the USB. Recently I have connected the USB but mine system not detected the USB and I have also found the yellow exclamation mark on the device manger which is not removing at all. Can anyone help on this?

    I might think you have issue on the USB controller driver and so therefore I would like to suggest you make updated the USB controller driver, if you have not updated the driver or your driver corrupted then you get the yellow exclamation mark on the device manger and so I would like to suggest you to updated the USB controller driver and after that your issue will get solved.

    If above all solution not working to solve the issue and then I’d like to suggest you to uninstall the USB controller driver on your system and after that install the USB controller driver from the official website of the Lenovo and after that let me know the issue. to do this you make right click on the my computer and after that select the properties. Now on the properties choose the hardware tab and under that make click on the device manger. Now on the device manger windows locate to the USB controller driver and after that delete the USB controller driver and then install the USB controller driver from the official website.
