标题:

USB Ports are not working.

文本:

I have a trash can mac that has non functional USB ports.  There is 5v at the ports but when any known good device is plugged into them it is not recognized.    I already replaced the IO board and it did not fix the issue.   Anyone seen this issue before and know what might be the cause?  The unit works perfectly otherwise..

设备:

Mac Pro Late 2013
