Unhappy perplexing modules composition...


Hey guys,
I have been working on reconfiguring my kernel to the new source code 2.4.22. I am running RH 9.0 on a toshiba satellite 1800. The reason for the reconfiguration is to revive my soundless soundcard.

I have everything working except for two miniscule problems. When the new kernel tries to load the new usb modules for my mouse and keyboard in the interactive startup, it tells me that the modules are not installed.

"initializing usb keyboard support: modprobe: can't locate module keybdev"
"initializing usb mouse support: modprobe: can't locate module mousedev"

Now in my kernel configuration in xconfig... I have the full hid support selected... plus the input core support... which includes...

"config_input_keybdev"
"config_input_mousedev"

So why am I still getting these errors?!? I am once again at my wits end...

Any help on this would be greatly appreciated! Thanks in advance!

"So why am I still getting these errors?"

In USB support you may have picked the wrong modules among EHCI, OCHI, and two
possible UHCI.

If your USB keyboard and mouse work in your old kernel you could compare your loadable module configuration between your old and new kernels with the find command:

find /lib/modules -iname "*mouse*"

find /lib/modules -iname "*keybd*"

find /lib/modules -iname "*ehci*"

find /lib/modules -iname "*ohci*"

find /lib/modules -iname "*uhci*"

find /lib/modules -iname "*usb*"

Hey Steve,
You sure are a great help! Thanks!

I am having a problem with selecting the ehci module. In my current perfectly working kernel, I have the ehci-hcd.o module installed. But when I go into xconfig to select ehci under usb support, for my new kernel it is not highlighted, so it will not let me select it. It does not tell me anything in the help tab about needing another module to select this one. Any help?

It is probably not highlighted because it is experimental (I didn't look in my xconfig to check). One of the very first settings in xconfig chooses whether or not to allow experimental settings.

Hey steve,
I am still having the same problem. I wouldnt even be able to count how many times I have recompiled this kernel.
One question I have is dealing with the difference of choosing yes in xconfig compared to module for an item. In the loadable module configuration for my current kernel, if an item is there, does it matter if I choose Y or M, in xconfig for my new kernel?
Could there be a conflict with the source code 2.4.22 and my toshiba laptop? I tried to install 2.4.21 but I had problems with the init durring boot. So I switched to 2.4.22 and it solved my problem.
Thanks Steve!

"In the loadable module configuration for my current kernel, if an item is there, does it matter if I choose Y or M, in xconfig for my new kernel?"

When you boot there is a period of time when you are running with the kernel but no loadable modules. If you need a modules during this period then you need to say y.

The Red Hat kernel has two ways to solve this problem. It can say y. But since Red Hat has to include every module that anyone might need this would make for a huge kernel. So the method that Red Hat uses is to compile every module of possible use as m. Then when Red Hat installs your system it makes an initrd which loads the necessary modules for your hardware configuration during initrd so that the initial kernel will have enough functions to run.

So it is possible that some of the USB modules should be y in your system. I don't know enough about USB to tell you which you need. Either ask somebody who knows or use trial and error along with educated guesses.
