That isn't surprising. The point is to identify what modules
are there, and see which ones look like they are associated.

Ah, then the USB I/F is likely not the cause. You may have a
basic chipset incompatibility. Maybe no interrupts, something
like that.

Not surprising. Nearly everything is likely an installable module,
and it likely uses an initrd. That won't work, unless you also
install an initrd, which you aren't if you are following the book.

I suggest using the kernel menu driven configurator, and configure
it according to what lspci shows when booted with anything that
runs. Using lspci will likely tell you what chipset you need to
have support for in the kernel. Build everything as internal,
not a loadable module.
