My computer has been operating for the last 12 months with no apparent problems. Now however all my USB ports have lost power, they operate a printer, mouse, keyboard but will not recognise my storage devices. I have tried a restore, update of windows drivers,
Can any body help?

Hi Dai
Thanks for the very speedy reply.
I have run 'MY Dell PC Checkup' Default scan, all items "passed"
I am not sure where in bios to check for usb enabled, Under bios POWER I have usb wakeup from S3 enabled
Under bois BOOT usb drives 1st drive "not installed'
When U refer to "uninstall all listed usb items" does this refer to Universal Serial Bus controllers ie. Intel universal Host Controller, 27CA,Cb,C8,C9,CC and also USB Root Hub
Also Human interface Devices, USB Input Device
My mouse is a USB device do I leave it plugged in or disconnect the power supply for the second reboot?
