Hello,
I have a driver for a USB device containing one ".c" and one ".h" file and no makefile. The computer is running fedora core 5 and linux kernel 2.6.15 I have everything I know to compile and install this driver, but have so far been unable. Any help in writing a suitable makefile or otherwise installing this driver would be much appreciated.

I think part of the problem is a messed up /lib/modules/2.6.15-1.2054_FC5/build file. In the file browser, it appears with two red circles with lines through them, one with a pencil. I assume this means no read, no write, but the permissions are set to allow reading, writing, and executing. Additionally, when I open the file in text editor, the file appears to be completely blank. In the file's properties, the file type is "link(broken)" and the size is 47 Bytes.

Thanks,
SEAP Four

You should be looking in /usr/srv/linux for .config (hidden file) which is the configuration for the current kernel. Look for it to see if the USB module you want is already conpiled. Look for that module in /lib/modules. If you don't find it, it's time to configure and compile your kernel to include the module of interest. If I remember correctly, there is an option to make a new kernel with an EXTRAVERSION option so that the new kernel doesn't replace the old one (that way you have a fallback option if the new one doesn't work).

You will need the kernel source installed to configure a new kernel.

Then add the kernel image to /boot, make a new initrd, and edit /boot/grub/grub.conf to add an entry for the new kernel (keep the old one until you are certain the new one works).
