I have had a USB hub attached that I have used since I got this Macbook Pro. Today I noticed that Time Machine, which is connected thru the hub, was not working. Then I attempted to get a file off a memory stick thru the hub, but that didn't work. So I plugged 2 different memory sticks into each of the USB ports directly on the MacBook and neither is recognized,  nor is my iPhone. So there is definitely a problem with the ports.


But how can both go bad at the same time? And is there a software upgrade the killed the ports and is there one to fix it? I am using Ver 10.6.8 with 2.53 GHz processor and 4 GB of DDR3 memory.


Thanx for any and all help.

MacBook Pro, Mac OS X (10.6.8)
