Sony Vaio USB ports not recognised by XP

Hi, I have a sony vaio PCV- RS704. Ever since we plugged an external hard drive into it (forgetting to plug both usb leads in, so it didn't get fully powered by the pc), none of the 7 USB ports work. Plug in any device and XP won't recognise it. We have tried the trick of deleting the USB stuff from device manager and restarting it; no good. We have also tried turning off the power management so the usb is always powered now. And there are no exclamation marks on the usb devices in device manager.
Bizarrely one of the usb ports at the rear connected to the printer can still send printing to the printer.
I know there is an expert out there who can help...

It is common problem on most of the PC USB ports does not recognise external hardware.It is mainly due to lack power supplied by the USB Ports..You can try with Old Pentium4 maschines.IT Reads well..

Another thing dont use extension ports to plug external HDD..always use backside on board ports.\

If the hard drive in the IBM laptop is OK then remove the hard drive from this laptop. Connect this hard drive to an USB hard drive adapter then connect the USB adapter with the hard drive into the USB port on the Vaio laptop. The Vaio laptop should see it as an external storage device (if the hard drive is OK). You can then open the various folders and files then copy these to the Vaio laptop

I have a Sony VAIO GRZ610, old i know. Won't power up,


If you cannot get the laptop working then try this method.
Remove the hard drive and connect it to an USB hard drive adapter and then plug this adapter into a working computer's USB port. If this computer sees this as an USB mass storage device (external hard drive) and you can open the various folders and files, then you can backup and or transfer your data to another computer. If yiu install the hard drive in an USB hard drive case then you can use this hard drive as an external USB hard drive.
