This mirrors what I got when I delved further into /sys. except there is
no 1-1.4:1.0/driver for the p54usb. Having the driver loaded but no
network interface created seems a little strange, but it does not appear
to be an installer issue because it also happens on a running system
without the firmware available.

Thank you for this. Both the zd1211rw and the p54usb worked flawlessly
after applying it.
