Thank you Mayer for the rapid response, sorry I have been slow in acknowledging your effort.

I had no idea that the two USB ports on this machine are not directly related.

Actually I thought they were both soldered onto the mother or logic board.

I have received another response aimed at fixing the port on the other side of the machine which apparently does have to be soldered.

I really do not know how I have managed to mess up both USB ports but I do carry a trackball mouse and portable HD which I am unpluging and plugging in all the time.

At any rate now I know what has to be done. I was in hopes there would be a way of either bending the tangs up or down for better contact and or using a rotary switch cleaner to etch and lube the ports for better contact.

Rest assured that I will be very careful with the ports until I can effect a repair.

Regards,

Ken
