Lost USB Support - Sort of.....

I'm in the middle of re-doing an inherited PC. Going along swimmingly. Haven't deleted the original user yet, but I've got my own setup almost complete. Whatever I just did (changed) seems to have killed the USB ports for thumb drives and rotary or SS USB-attached drives. The mouse dongle works fine, as does a BT adapter I just tried. The insertion and removal tones sound, but no action occurs, nor can I see the drives in "My Computer".

They (USB-2 and USB-3 ports) were working properly twenty minutes ago so I'm SURE it's something inadvertent (stupid) that I did. I'm at a loss.

Any (and all) thoughts would be appreciated.

Thanks.

If I knew what I'd done I could probably reverse it. I was tweaking various settings, autoplay being one of them, and it just happened. My problem is that I tend to be in a rush about this stuff and, as now, get in trouble! I can always re-install but that;s a real pain after all the work I've put in. THan ks for any ffurther thoughts.

ps: Win 7 Pro

Thanks. That worked. I'll keep this in mind for the next time.
