Sorry to sound ignorant. I purchased a new 1mac 1 month ago. I set it up the parallels and windows 7. everything worked fine for 3 weeks then one day all the usb ports stopped working. Did I push a wrong button? Turn it off somehow? Can anyone help me with this problem? Thanks in advance.
 
Have you tried an SMC reset yet?
Intel-based Macs: Resetting the System Management Controller (SMC) (Apple Support Site)

If the first link does not work, as the Apple Support Pages are bit funky these last weeks:
Intel-based Macs: Resetting the System Management Controller (SMC) (PDF from that Apple Support Page about resetting the SMC)​

It helped me before.

And what does System Report > Hardware > USB have to say?
