A technician installs a legacy PCIe expansion card in a Windows 10 desktop. After rebooting, none of the front-panel USB ports work, and Device Manager shows the USB xHCI controller with a yellow warning triangle and the message "This device cannot find enough free resources that it can use (Code 12)." Which action should the technician take first to resolve the USB controller resource warning without removing the new card?
Download and install the latest chipset driver package from the system manufacturer.
Replace the existing USB cables with shorter, shielded versions.
Disable USB selective suspend in the computer's advanced power settings.
Reformat the system drive and restore Windows from a recent image backup.
Code 12 indicates that two devices are requesting overlapping I/O ranges, IRQs, or memory addresses and Windows cannot allocate additional resources. Updating the motherboard's chipset drivers often provides an updated INF and resource map, allowing the Plug-and-Play manager to reassign resources so both the USB controller and the newly added PCIe card can coexist. Changing USB power settings or cabling will not address a resource conflict, and reinstalling Windows is unnecessary for this type of issue.
