Re: i386 vs i686 was Configured kernel source code ... What …

Have no fear, George. I think most of the USB problems were related to
early 2.4 kernels. I'm thinking that with hotplug baked into the 2.6.n
kernel, things should go fairly smoothly.

From what I can tell in the readme, I'd try this:

1) Install kernel development packages
This may or may not be necessary, as much of the necessary "build chain"
(stuff you need to build kernel modules from source) is installed by
default in CentOS. Do a "rpm -q kernel-devel" on a command line. If it
shows you a kernel-devel version, you're probably good to go. If it
doesn't, add the development packages using Applications->System
Settings->Add/Remove Applications, then check Development Packages and
click Update, which will install what you need from CDs.

2) The makefile for your driver expects the kernel source to be at
/usr/src/linux. Yours is somewhere else, so create a symbolic link to
point to yours:
ln -s /usr/src/kernels/`uname -r` /usr/src/linux
Alternatively, you can:
export KSRC=/usr/src/kernels/`uname -r`
before doing the make commands, but I think the symbolic link is easier
since you only have to do it once (the export KSRC variable is only good
for the terminal window, or shell instance that you issue it from). Just
be sure to change the link if/when you rebuild the driver for a newer
kernel.

3) Copy the kernel configuration file to your source tree:
cp -p /boot/config-`uname -r` /usr/src/kernels/`uname -r`/.config

Note, `uname -r` in the examples above are back-quotes (or back-ticks).
They tell the shell to execute what's contained in them and put the
results in its place. In this case, the uname -r command fetches the
kernel version that's currently running.

Follow the rest of the readme instructions, and you'll probably be good
to go.

Other observations:
1) You might be able to use the gui on CentOS to configure your wireless
parameteres (as long as you're not using WPA). I've done so with Fedora
and CentOS, but that was with PCI, not USB. YMMV.
2) You might want to take notes as you go, and write a more detailed
CentOS-centric HowTo for the device driver. That would be useful to
others who proceed down this path. I presume that it would also be
user-friendlier than the readme. Don't blame the readme writer though,
as configuration for wireless varies among the distros, and they need to
stay distro-independent.

Let us know how you `make`. :)
