    I have a desktop PC which has USB ports on the front and the back sides. I tried plugging in a flash drive (works well on other PCs) on both sides but there is no response. i checked on the device manager the properties of the USB ports and it says its working properly. i checked at the BIOS to make sure its enabled, i shut down and removed the power cord, plugged it back in and restarted the pc, uninstalled and reinstalled my USB controllers. i was still not successful. i opened the CPU and the physical connections inside and there seem to be no problem.

    There is though this one suspicious Unknown Device under the Universal Serial Bus Controllers. Its properties says that there are no drivers installed for the device. I ran DriverGuide Toolkit to get more details on this device but this is the only info i could get:

    Class: USB
    Version: 5.1.2600.0
    Date: 07/01/2001
    Manufacturer: (Standard USB Host Controller)
    Capabilities: 0
    Class: USB
    ClassGUID: {36FC9E60-C465-11CF-8056-444553540000}
    CompatibleIDs: USB\UNKNOWN
    ConfigFlags: 0
    DeviceDesc: Unknown Device
    HardwareID: USB\UNKNOWN
    LocationInformation: USB Device
    Mfg: (Standard USB Host Controller)

    I'm not sure if this device has anything to do with all the ports that are not working but if you have any idea what might be going on with my PC, I am dying to hear from you. Thanks!
