There is a config that works, because my USB ports work on CentOS, but I am tired of fighting the issue. I simply want a recommendation on a chipset or PCI board that works under LFS. And that's kind of hard to answer, because *all* of them should, including your current NVidia one. If USB works for you on CentOS, it's not a question of whether it's supported by Linux or not. It has to be something in your config, and if so, changing the hardware is unlikely to make any difference. For what it's worth, these are the config options I have enabled relating to USB (everything is a module, not built-in). * Device Drivers - USB support - Support for Host-side USB * Device Drivers - USB support - EHCI HCD (USB 2.0) support * Device Drivers - USB support - OHCI HCD support * Device Drivers - USB support - USB Mass Storage support That's it. I've been using that configuration on various machines for years, including the NVidia chipset I'm currently running, and another one before that.

I'd be happy to get any keyboard and mouse to work. Here is a link to
the Knoppix problem, where none of the input devices work: I used a
Knoppix dvd that arrived with the Linux Magazine a while back.
Debian, upon which KNOPPIX is based, used to have/has problems when you
have both a USB keyboard and a USB mouse, but just a USB keyboard
seemed to work fine. I didn't try just a USB mouse. When I had the
problem, both the keyboard and mouse were dead. I reported this
a couple of years ago, and was told by a member of the support team
that this behavior was impossible. I didn't pursue it, due to the
rather emotional nature of the response, and I'm reasonably sure it
wasn't investigated further.
About a year later, another guy with the same problem contacted me
off list (due to the emotional response I garnered) asking whether I
were ever able to resolve it, which I had not, since I no longer
administer any Debian based machines. So, in the intervening year
or so, I'm certain it wasn't pursued.
Anyway, you might try replacing the USB mouse with a regular one,
either PS/2 or serial port, and see if you can use the machine that
way, until you resolve whatever the problem is.
If there is an accepted trouble ticket, then perhaps it'll get tracked
down now, and fixed.
With the Debian support team, very much YMMV, IMO. Linux is
practically a religion with some of the pro Debian people,
though mostly the support team is rational.
I like KNOPPIX, and use it as a rescue CD, but being based upon
Debian, and often Debian Unstable, it's definitely in my
considered experimental list. I've been disappointed somewhat
by KNOPPIX 6.x so far. KNOPPIX 5.x was a better release, IMO.
You might download an image of KNOPPIX 5.3.1 and try that,
if you want a version of KNOPPIX which works. I can recommend it.
It may have the USB keyboard+mouse problem, however. I don't like
to use USB devices much, anyway, so I can't test for you since I
don't have a USB keyboard at present.

I would agree with this except that the kernel is such a rapidly
moving target, it would require a nearly complete rewrite with each
new kernel release. Describing the kernel configuration would require
increasing the size of the book by quite a bit, and it would be a very
high maintenance part of the book.
Perhaps just a hints section about how to ascertain what hardware
is present could be added, however. Perhaps also how to ascertain
what modules got loaded by the 6.3 LiveCD could be put in, so
one might have an idea what to build in.

That isn't surprising. The point is to identify what modules
are there, and see which ones look like they are associated.

Ah, then the USB I/F is likely not the cause. You may have a
basic chipset incompatibility. Maybe no interrupts, something
like that.

.config and tried to use it to build a kernal:

Not surprising. Nearly everything is likely an installable module,
and it likely uses an initrd. That won't work, unless you also
install an initrd, which you aren't if you are following the book.
So now I went back to building a clean kernel that will at least boot again.
So to state it again, none of the inputs work after I make the kernel
selection from the menu. The last time I made this selection I was
not using the USB, I was using XT and PS/2 mouse.
I suggest using the kernel menu driven configurator, and configure
it according to what lspci shows when booted with anything that
runs. Using lspci will likely tell you what chipset you need to
have support for in the kernel. Build everything as internal,
not a loadable module.

build 6.6 before attempting to proceed with BLFS.
If I need later than 6.4, then...

the 6.3 LiveCD and download jhalfs, and let it go to work.

For example, I have no idea what ohci1394 is. If you look at the help in menuconfig, it usually tells you the modules will be called. So find -name Kconfig | xargs grep 'called ohci1394' and then look at the Kconfig file that matches (that one is for firewire, aka 1394 or ieee1394). Also note that although you probably have the hardware (i.e. a chipset which has a 1394 port) you weren't using it when you ran lsmod, so you might not need it. In general, the best advice is to review your hardware (e.g. use lspci), and build in everything you know you need. If desperate, or if you have problems (such as your usb problems), one possible approach (apart from the suggestions already made) is to make everything that looks perhaps-related as a module. Once you have a kernel, test it to see if you can do everything you expect to do on the host system. Udev is now reasonably good at working out what to load for the hardware that is present, but each individual version of the kernel brings new bugs. In general, if people have a modifiable host system, and it is recent enough to build the kernel you are going to use in LFS, I recommend that people do that (_without_ an initrd or initramfs) - and keep tweaking it until it works sufficiently *before* they start LFS. ĸen -- After tragedy, and farce, OMG poneys! -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
