USB Keyboards with recent 2.4.19-pre/rcXX and 2.5.2X

USB Keyboards with recent 2.4.19-pre/rcXX and 2.5.2X

[Sven.Riedel]

Hi,
USB keyboards don't work with recent 2.4.19-preXX (-pre2 works fine for
me, but pre-10 and up don't), as well as int (at least) 2.5.25.
The kernel does find the keyboard during bootup, but doesn't accept any
keypresses. This happens regardless of the UHCI driver selected in
2.4.19 (normal or JE). 
Input core support has been compiled in, as well as the full HID.
Verified on one different machine.

Regs,
Sven

Is CONFIG_USB_HIDINPUT selected in your .config?  You _did_ run 
'make oldconfig' when upgrading kernel versions, right?

Ah, and I didn't believe people when I said this wasn't going to be a
problem...:

EVERY TIME you move a different .config file from a different kernel
version you HAVE to run 'make oldconfig' to fix up the differences.
This means everytime you upgrade your kernel version, you have to do it
before rebuilding the kernel.

I think the 2.5 Makefile now detects this condition and will tell you to
run it.

Nope, that's what 'make oldconfig' is there for.  That combined with
reading the help entry for the new config items would have told you that
this was a necessary thing for you to enable.

For your sins, I sentence you to two weeks of user support.

This isn't strictly true. You could do any of the make config versions,
[make config, make menuconfig, make xconfig, make oldconfig]
but you have to look at every new option, and that is a bit error prone
(because you missed something subtle, or you were hasty, whatever).
make oldconfig helps you here, because it gives you only the new
options, which is probably what you want.

Some people always like to run make xconfig as well, because Rusty
says "it is the only one with a static parser" (or something like that).
If you do this, you don't need to change anything - just save the config
again.

Hm, can I use "previous time served" on linux-usb-users and here as a
credit for this sentence?  :)
