What action should be taken if a device runs in USB 1.1 mode instead of USB 2.0 mode?

The correct choice highlights that editing CMOS settings to configure USB ports can potentially resolve issues related to USB mode. USB ports might operate in a limited mode due to specific settings stored in the BIOS/CMOS configuration. It's possible that the USB controller settings or the configuration of USB legacy support could influence whether devices operate at USB 1.1 or USB 2.0 speeds.

Accessing the BIOS or UEFI firmware during system startup allows you to check these settings. If USB support is configured incorrectly or not optimized for higher speed standards, adjusting these settings can enable full USB 2.0 functionality.

Other options, such as replacing the device, updating motherboard drivers, or reinstalling the operating system, may not address the direct configuration issues that could limit USB performance. Replacing a device might not be necessary if the settings can be adjusted for existing hardware. Updating drivers is useful but may not resolve hardware-level limitations resulting from BIOS settings. Reinstalling the operating system is typically not an effective action for resolving hardware compatibility issues like USB mode limitations.
