Mac Pro 2013 - USB port not working after CMOS battery replacement

I've a 2013 Mac Pro cylinder. I was facing issue with powering it on, after multiple try I used to successfully make it work. Later I realised that there is a problem with the CMOS battery.


Now after replacing the CMOS battery, the unit is starting but all the 4 USB port have stopped working.


Thunderbolt ports, HDMI port & lan ports are working perfectly fine.


The USB is drawing the power but is unable to detect any devices including external keyboard and mouse.


I'm able to access the machine with screen share option from my other Mac.
