Problem mounting USB ports after installing Tahoe 26.1

My MacBook Pro 14'' M1 does not recognise any of the 3 USB ports after I upgraded to Tahoe 26.1. I tried other cables reinstalling OS and moving the hard drives between the USB ports. The hard drives can be mounted on other MacBooks Any assistance will be welcomed

MacBook Pro 14″, macOS 26.1
