Hi,
I'm trying to write a device driver, using FedoraCore5 (kernel: 2.6.15.-1.2054.FC5) According to the documentation I've build a tree as a user and compile my module against it. I want to enable some debuging that isn't enabled. Also I need to recompile some existing module (/drivers/usb/input/hid-core.c) as I've added some lines in there.

I did:
make menuconfig
make dep
make clean
make bzImage
make
make install
make modules
make modules_install

...but when I reboot, the system crashes! Obviously I make something wrong.

Some Information:

kernel tree is under:
/home/user/rpmbuil/BUILD/kernel<version>/linux<version>/

the changes I described above concern the addition of the vendor and product id into the blacklist of usbhid in order to get my driver probed.

Plz help!

Try again this time (the correct steps [in the proper order] for the Red Hat family you need);

<apply the your patches here>
make mrproper
cp /boot/config-2.6.15.-1.2054.FC5 .config
make menuconfig (or gconfig or xconfig)
make
make modules_install
make install

The cp the config file step is optional and may not be the correct name for config file but it should give you an idea of where a working configuration resides.

Thank you very much!! It really helped me! It worked ok! Although I should have asked erlier It would have saved me 5 days!!
Thanks again!!

Your welcome, glad to help.
