I have a Sony VGN-T1XP Vaio laptop with an Intel Pentium M Processor running XP Pro SP2. For some reason the two USB ports have stopped working and no USB devices are recognised. I have looked at the device manager under USB controllers and there are four USB controllers listed which are as follows:
Intel 82801DB/DBM USB 2.0 enhanced host controller 24CD
Intel 82801DB/DBM USB universal host controller 24C2
Intel 82801DB/DBM USB universal host controller 24C4
Intel 82801DB/DBM USB universal host controller 24C7
Underneath those are four USB root hubs.
I have previously used a USB card reader and external hard drive on both ports without any problems but now when I connect any device nothing at all happens.
I have deleted and reinstalled the USD controllers to no avail and I have created a new user account but this has an identical hardware profile as the main user account.
I suppose I could reset the machine back to the factory settings but would prefer to avoid this.
I have tried to be as specific as possible but I don?t really know much about what I am doing so apologies if I have omitted something.
Can anyone help please?
Thanks and Happy New Year!
