Hi
I think there is a bug in kernel 2.4.19 under the usb section. I
proceeded to build kernel 2.4.19 on a RH7.3, DELL SMP system. I have a
wireless usb mouse, usb SanDisk, etc. Anyway the problem showed up when
I was trying to get the usb mouse to work. This is not a new system ...I
did have all the hw and sw components working under 2.4.5.
The default for the USB section is to included USB support (y) in the
kernel. I am assuming the usbcore.o got incorporated into the kernel
build tree during [make dep; make bzImage; make modules; make
modules_install]. I continued to get mousedev errors ...verified that I
had mouse support, hid support, uhci support, all this look good. As
soon as I changed "USB Support" from (y) to (m), i.e. made usbcore.o a
loadable module WALLA! usb devices started to work. Question: Is there a
bug with (y) support for "USB Support" ?
I also noticed usbdrv.o resulted in errors when included (y) in the kernel:

Any ideas ?
Right now I am using usbcore.o as a loadable module and every thing
works fine.

Take Care,

It has been reported before, but I couldn't reproduce it.

Can you provide an exact copy of the CONFIG_USB and CONFIG_INPUT lines from
your kernel .config for a working case, and a broken case?

This is probably important :-|
Looks like some include breakage. I'll take another look if you send me the
two cases for the kenrel .config.

No, you need to set CONFIG_INPUT to y if you are also selecting the HID
driver to be compiled into the kernel. That should solve your problem.
