To access the context menu, open Windows Explorer and select 'My Computer.' Go to the Hardware menu, Device Manager, and the Universal Serial Bus Controllers subheading. To reveal more options, select the plus sign. If your system has USB 2.0, you'll see an entry labeled 'USB2 Enhanced Controller;' if there's a yellow warning icon, the corresponding device or driver is malfunctioning. If you do not have the necessary USB 2.0 drivers loaded, you will not see USB2 Enhanced Controller when you expand the Universal Serial Bus Controllers menu. If you need to update your USB 2 drivers, you may either manually do it or utilize a Driver Update Tool to do so automatically.
