    Hi aneeqtariq_143,

    May I know the operating system installed on your computer.

    You may uninstall the USB root hubs and check if it makes any difference. To uninstall USB Root Hubs:

    • Press and hold the Windows key and press 'R' key. This will open the run window
    • Type 'devmgmt.msc' without the parenthesis, click on 'Ok'
    • Expand ‘Universal Serial Bus controllers’
    • From the list, look for ‘USB Root Hub’
    • Right click, choose ‘Uninstall’, choose ‘Ok’
    • Uninstall all ‘USB Root Hub’ listed
    • Wait for all the drivers to get uninstalled
    • Restarted the computer'. Restarting the computer will install ‘USB Root Hub’s automatically on the computer

    Hope this helps.
