Okay, I'm getting to the point where I can reliably compile a kernel
and the appropriate utilities. I'm not sure why the modules are getting
compiled with the extended versioning and the kernel isn't, but
I've turned on versioning in the kernel and I appear to be able to load
my various modules.

However, now I'm trying to figure out how to get the USB stuff working.
When I plug in my USB devices, I get messages from the kernel. I
can even load the appropriate modules with modprobe. However, lsusb
gives me nothing (even with -v), and /proc/bus/usb is empty, and
whatever's supposed to be creating the devices isn't running or
working either.

Is getting automatic recognition and loading of USB modules, and the
creation of the appropriate devices for them fairly automatic?

Thanks!

Hello,

I was looking at your message on kernel compile, and just I wanted to say this, that compiling a kernel is not a problem. Actually it is problem, but once you get the hang of it, then you know how to move the files, and to keep the proper version of drivers and the rest of the files that required for configuration. Because after all, you can compile a kernel and send it onto the board. However I think, the proper working of the kernel with the drivers and the hardware is itself a big issue.
And about USB I have also something to say, that at least my USB is not working on the board I am using, while I have everything configured accordingly. I just can't figure out why, everything looks normal, and what's more it was working before just on a different board but the same configuration.

Thank you and regards.

Okay, /proc/bus/usb is, apparently, a red herring, because (duh) the
devices file isn't on my development laptop either.

Digging further, this is normally handled by "udev", but "udev" is
hidden because BusyBox is supposed to provide these features. So,
figuring out why BusyBox isn't doing the right thing is my challenge.

And I still need to figure out why lsusb isn't giving me any output.

Okay, I'm chasing this further.

I've got a Linux kernel 2.6.24.3 compiled with buildroot and the latest
at91sam9261ek_defconfig off of linux4sam.org, with both the "USB device
filesystem" and "USB device class-devices" enabled, but lsusb has no
output.
