USB and Bluetooth Dead at Boot

After updating software this past week, Zorin boots without USB or Bluetooth support. My keyboard and mouse are not active so I can't get past the login screen. My pc does not have a keyboard or mouse port and I do not have a touchscreen so I have no way of turning these services on. I have re-installed Zorin 16 Pro but the problem persists. When I boot into Windows, usb and BT are fine so it's not a hardware issue. Any advice appreciated.

Some computers have USB support in The BIOS settings. Have you checked that it is enabled in BIOS?

Thanks for responding. The BIOS was the first thing I checked and both BT and USB are turned on.

I guess roll-back to previous kernel to test may be a good idea. i.e. boot with "Zorin Additional Options" and choose previous kernel.


Turns out that a software update to the 5.13 kernel was the culprit. Booting back to 5.11 resolved the issue. If anyone had the problem and resolved it while staying on 5.13 I would appreciate knowing how you did it.
