Is your Mac on the most updated software? That's a good point to start from.

I have installed last update and tried to rest SMC and NVRAM and the same problem
my next step would be to wipe the computer and reload the os. If that dosent do it try re seating the ram.
@dasrepair - I don't think this is a software issue. A bit more testing will tell us which part of the logic board needs repairs - Power or Data.
@danj yea i agree to that. i tend just eliminate software first and then take it to the hardware.
@danj how can I check if it power or data issues?

Do you have a problem with both ports?
Do you have a powered USB hub which you can use? See if that works.
