I tried building a 2.4.13 kernel with USB support as built-in, instead
of modules. The system worked, and USB devices worked, but there were
no entries in /proc/bus/usb Yes, I had enabled both /proc filesystem
and USB /proc filesystem support. When the same kernel was built but
with USB support as modules, the /proc/bus/usb entries appear.
Although no expert in these matters, I suspect that when the USB
subsystem is built-in, it is initialized before /proc is mounted, and
the USB /proc filesystem support either turns itself off or puts the
"files" elsewhere.
A viable solution might be to have make menuconfig warn against this
combination.
Dan.
