I can reproduce this on my 4GB Pi4 with the 64bit image. This does not seem to be an issue with the 32bit image in my quick testing. With the 32 bit image, both the keyboard and external storage are detected and working.
As you can see here with my USB keyboard and thumb drive attached, they are detected when running the 32bit image: ubuntu@ubuntu:~$ lsusb Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 04d9:0006 Holtek Semiconductor, Inc.
