What configuration should you change if a device connected to a USB 2.0 port runs in USB 1.1 mode?

1. Edit the CMOS settings to use USB 2.0

2. Update the device's firmware

3. Replace the USB cable

4. Connect the device to a different computer

The correct answer is: Edit the CMOS settings to use USB 2.0

To address the situation where a device connected to a USB 2.0 port is operating in USB 1.1 mode, changing the configuration in the CMOS settings to enable USB 2.0 support is an appropriate step. The CMOS (Complementary Metal-Oxide-Semiconductor) settings govern the basic hardware configurations and settings of the computer. This can include enabling or disabling features related to ports, such as USB support. If the motherboard or the device's BIOS settings have not been configured to recognize and enable USB 2.0 capabilities, the device may revert to operating at the slower USB 1.1 standard, even when connected to a USB 2.0 port. Adjusting the CMOS settings ensures that the higher-speed capabilities are activated, allowing the device to operate as intended. Updating the device's firmware might help in improving compatibility or resolving operational issues, but if the underlying hardware’s capability isn’t set correctly in the BIOS/CMOS, the device will still function at the lower speed. Replacing the USB cable or connecting the device to a different computer may be less effective since the original problem stems from the configuration settings rather than the cable or system compatibility with the device. Thus, altering the CMOS settings is the
