Why would all USB devices now be Not Recognized in Vista?

Doc Logic
Working Devices suddenly are not recognized. Internal AcerOrbicam failed, flash drive failed, mouse failed, digital camera failed. All were working for a long time??? Suddenly all are device not recognized?? Tried Regedit and removed usbstor to force re-id of devices - no luck. Driver re-installs say no device? Also removed-reloaded USB hub controller device managers, which re-installed and again detected "Unknown Device". Vista on Acer Aspire 5100, many different Oribicam models used and cannot find out which is in this laptop (not even from Acer!!). Do not suspect camera problem, just USB failure.

    If so and they became available Tuesday last week so anytime after that they could have been applied it's possible that one of those Patches/Hot Fixes broke the USB Devices/Driver in your Computer.

    You could try restoring your system to a time before any M$ Patches where applied and see if that makes any difference.

    Which version of Vista do you have loaded a 32 or 64 Bit Version as the drivers for one may not suit the other. Generally speaking you can not use 32 Bit Drivers for 64 Bit Systems or 64 Bit Drivers for 32 Bit Systems.

    - Also What i like to do is boot the system with a linux boot cd (can accept hot pluggin usb devices)or UBCD4win (need to have the devices pre plugged in to be detected) and see if the devices are detected
    This will at least prove the hardware is ok, and then we only need to trouble shoot the software

    thats when you can try doing a system restore or uninstalling the updates from a time prior to it not working.
