Have you perhaps disabled the device in the BIOS?

USB Legacy is not quite related.

What happens when you connect an USB device?

What version of Windows is installed?

What were the problems with the PC prior to putting it away?

hi
the problem was ultimately solved by taking out the CMOS battery for a couple of minutes with the help of www.usbman.com

anyway thanks for your support and time.

That's not right. Your CMOS battery might be running low if the BIOS is acting up. You should replace it just in case.
