Rasberry Pi 4 has no USB

[Carl Johnson]

I have an 8GB RPi 4B that I am trying out, but it has no USB response at
all. That means that I can't use a keyboard or mouse, but I can use a
serial console and ethernet.  I can plug any USB device into any port,
but there is nothing logged in /var/messages.  Running usbconfig as root
just reports 'No device match or lack of permissions'.  Running
'dmesg | grep -i usb' reports only the following lines:

  usb_nop_xceiv0: <USB NOP PHY> on ofwbus0
  bcm_xhci0: <VL805 USB 3.0 controller (on the Raspberry Pi 4b)> irq 81 at device 0.0 on pci2
  usb_needs_explore_all: no devclass
  
Running 'pciconf -lv' shows there is a VL805 USB controller present.  I
tested this with Linux and everything worked properly.  This is a new
computer that I bought only a couple of weeks ago.  Does anybody have
any ideas on what this might be, or what I could do to try to figure it
out?

Thanks in advance for any ideas.
