Are either of the /proc/bus/usb or /dev/bus/usb filesystems mounted? ('mount' will list all of them)

I'm confused that you can see output from lsusb, but maybe that is consulting /sys/bus/usb.

Correct, running the driver with any -D flags will log debug output to the console, and will prevent the driver from going into the background.
