Subject: USB Keyboard


Hello all,

I have been using linux-2.6.16.24 for development.
However, when I boot a sustem that uses a Dell USB
keyboard with a hub built into a Dell monitor, there
are continuous keyboard disconnect messages until
I exercise ^S/^Q. Then, everything is fine. I
thought maybe there was a bug that had been fixed
in later versions so I built and installed Linux-2.6.22.1.
The required usbhid.ko doesn't build, even though it
is enabled in ".config."

Could you plase send me your full .config? The usbhid module builds just
fine, please doble check on your side.

Thanks,

Okay. I found what was different. It does actually build, but it
is now put into a completely different directory,
/lib/modules/2.6.22.1/kernel/drivers/hid/usbhid, and requires
/lib/modules/2.6.22.1/kernel/drivers/input/ff-memless.ko
to be installed before it can be. None of this is documented
and it makes upgrading extremely difficult, expecially when a
keyboard won't work anymore.

BYW, it did fix the problem with the old driver.

Only if you enabled force feedback for HID devices in your menuconfig. And
if you did so, it perfectly makes sense that the force-feedback input
module must be loaded.

1) what strange distro/environment do you use that the usbhid driver is
not loaded automatically when you plug the keyboard in?
2) even if your module autoloading is that much broken, you can always ssh
to the box or attach PS/2 keyboard and modprobe usbhid ... that works
no matter which directory keeps the driver

There is nothing to be documented there, we don't document which directory
holds which driver.

Good to hear, thanks.
