    every few hours my work PC loses a USB hub, and the USB port stops responding.

    Im on the Z77 Extreme9 Bios package from ASRock 🙏 Ive seen people mention USB selective suspend, power management, and chipset drivers. Id love to understand which one is most likely, cuz changing all of them at once wont tell me anything. Im happy to test one thing at a time and report back with results. seriously need help here 😭

    if eevrything fails and ports die even in a fresh Windows install or in a Linux live USB, the problem is hardware (motherboard or power), not drivers.

    oof check Event Viewer > Windows Logs > System around teh disconnect time for events from USBHUB3, USBXHCI or Kernel-PnP. errors there point to the controller driver or power issues. fingers crossed 🤞

    Disabling selective suspend costs a little battery on laptops. I'd use it as a diagnostic first, then decide.
