Thread: High Speed USB ports on Equium A100

  1. High Speed USB ports on Equium A100

    I installed an Advent webcam (before exchanging it for a better creative one). Part of the installation process involved installing a USB controller from Microsoft. (OS is Windows XP Home). I uninstalled the Advent software when I returned the webcam.

    Since then I've started to get messages every time I plug in a USB device, about a high speed device needing a high speed port.

    When I look in Device Manager, I have two sets of USB Serial Bus Controllers:

    The first one includes 2 standard OpenHCD USB Host Controllers, 2 USB composite devices, 1 USB printing support, and 2 USB hubs. Their drivers are dated 2001.

    The second one includes 1 PCI class USB 2.0 Enhanced Host Controller and 1 USB Root Hub Device. Their drivers are dated 2006.

    I have 4 USB ports and all seem to be using the first set of USB controllers. If I disable any of the controllers, then various USB devices stop working.

    As my laptop is only 18 months old, I would have thought that all USB ports were version 2.0?

    How can I 'force' the laptop to use the second set of controllers?

    Hi there,

    I think the biggest problem is you would waste more time to fix such an driver related issue then just grabbing the recovery CD and performing a recovery of your whole system.

    Maybe the fastest way to bring some high-speed life back to your USB 2.0 ports. Otherwise I had suggested to remove all ports from the device manager and let windows after a restart reinstall all drivers, But before you perform the restart it would be better to remove manually ALL previously installed drivers.

    Maybe it helps, but if not it would definetively better to perform the recustomization..
