There's no warning because the driver doesn't know anything is wrong. Even though it may not find any devices to manage when it first gets loaded, there's nothing to prevent you adding, for example, a PC-card with a USB controller on it at some later time. That's true in general for most Linux drivers. (The ones that aren't platform-specific, anyway.) They don't look for devices to manage at load time; instead the driver core calls their probe() routine later on. Consequently drivers can't tell at load time whether there will be any useful work for them to do.

I will remove the Oh I see, looks like I have been deleted from CC in the middle of the thread, so sorry for superfluous reply.

I will try it in the morning. It's now past quitting time and, following this thread, you will note that the ohci module needed to be loaded for this AMD unit so the keyboard now works! I will remove the unused modules tomorrow morning and post hopefully good news. I used the usbkbd module in a blind attempt to get things working (I have been following a lot of suggestions).

Or is there any special particular reason for you doing so? This module is not what should be used in a normal situation on production and fully working systems. Everything for USB keyboard to work is normally handled by the usbhid module. Please see the description of what usbkbd is: config USB_KBD tristate "USB HIDBP Keyboard (simple Boot) support" depends on USB && INPUT ---help--- Say Y here only if you are absolutely sure that you don't want to use the generic HID driver for your USB keyboard and prefer to use the keyboard in its limited Boot Protocol mode instead.

If even remotely unsure, say N. The module could be buggy, your keyboard might be hidbp incompatible, or whatever. usbkbd is very rarely used and is there only for really special ocasions, as the Kconfig help text clearly states. So could you please try without this module loaded and let me know the result? -- Jiri Kosina - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

It executes a simple home-made shell which has three commands, one to check if all the hardware is present, another to install software, and the last to umount the drive(s) and reboot. The rest of the CD/ROM contains a tar.gz ball of the entire software to be installed after the shell partitions the drive(s), builds file-systems, and mounts them. After the entire directory structure with all the files is cloned, `grub` is executed to put the boot-sector on the first partition of the first drive. This is how we 'clone' a number of embedded image-processing systems. It is only __after__ all that happens that I have a system that can be used interactively. It doesn't normally run on a network, but it could once it is completely built. Using this technique, one doesn't need to have some technicians install a distribution from scratch, then install all the third-party stuff, then install all the Analogic stuff. We just 'clone' a "golden" system, which takes about two hours per system as opposed to about 8 hours the "hard" way. The time is basically the time to read from the CD. The OS on the CD is a standard 32-bit version as the attached ".config" file will show. It boots these systems fine because it doesn't do anything special, only claims to be a Pentium, etc. So, this worked with RedHat versions of the kernel. However, we now have some third-party software that doesn't so I built another CD/ROM that contains a new tarball plus a kernel from the net. That's when I found that the USB keyboard doesn't work on most of the systems, but still works on some. The initrd "linuxrc" file that loads the modules is here. One can see the order in which the modules are loaded. We had to make our own shell to replace 'nash' because the SCSI drivers spawned "children" that confused nash with SIGCHLD when they executed. #!/bin/command echo "Mount /proc filesystem" mount -t proc /proc /proc echo "Loading modules" echo "Loading scsi_mod.ko module" insmod /lib/scsi_mod.ko echo "Loading sd_mod.ko module" insmod /lib/sd_mod.ko echo "Loading scsi_transport_spi.ko module" insmod /lib/scsi_transport_spi.ko echo "Loading aic79xx.ko module" insmod /lib/aic79xx.ko echo "Loading jbd.ko module" insmod /lib/jbd.ko echo "Loading ext3.ko module" insmod /lib/ext3.ko echo "Loading loop.ko module" insmod /lib/loop.ko echo "Loading rtc.ko module" insmod /lib/rtc.ko echo "Loading uhci-hcd.ko module" insmod /lib/uhci-hcd.ko echo "Loading ehci-hcd.ko module" insmod /lib/ehci-hcd.ko echo "Loading usbhid.ko module" insmod /lib/usbhid.ko echo "Loading usbkbd.ko module" insmod /lib/usbkbd.ko echo "sleeping for a few seconds" sleep 2 echo "Mounting root filesystem" /bin/findroot mount -o defaults --ro -t iso9660 /dev/root /sysroot pivot_root /sysroot /sysroot/initrd umount /initrd/proc exec /sbin/init On the systems where it works, one can unplug or plug in the keyboard and get a corresponding message. On the ones that don't, it's dead. I was going to boot a troublesome system again and report results on the screen with debugging enabled. However, that system is now having its software loaded the "hard" way because they need to make shipments. They will soon find out that they can't complete the installation because the keyboard doesn't work once Linux is up, but they didn't listen I will be able to boot it again after they finish failing (tommorrow)!
