How to install sda1, sdc1, idec1 devices?

I am trying to install new devices in /dev but nothing is happening. Are the below devices (/ect/devfsd.conf) compatible with AL's bsd style?

# If you have removable media and want to force media revalidation when looking
# up new or old compatibility names, uncomment the following lines
# SCSI NEWCOMPAT  /dev/sd/* names
LOOKUP        ^(sd/c[0-9]+b[0-9]+t[0-9]+u[0-9]+)p[0-9]+$    EXECUTE /bin/dd if=$mntpnt/1 of=/dev/null count=1
# SCSI OLDCOMPAT  /dev/sd?? names
LOOKUP        ^(sd[a-z]+)[0-9]+$    EXECUTE /bin/dd if=$mntpnt/1 of=/dev/null count=1
# IDE NEWCOMPAT   /dev/ide/hd/* names
LOOKUP        ^(ide/hd/c[0-9]+b[0-9]+t[0-9]+u[0-9]+)p[0-9]+$    EXECUTE /bin/dd if=$mntpnt/1 of=/dev/null count=1
 IDE OLDCOMPAT   /dev/hd?? names
#LOOKUP        ^(hd[a-z])[0-9]+$    EXECUTE /bin/dd if=$mntpnt/1 of=/dev/null count=1

It shouldn't be necessary to 'install' anything in /dev. That's what the devfs daemon is for.

I noticed in the default kernel modules that scsi was built as a module so you will need to load this at the very least. However, modprobing any specific scsi device should pull in the scsi module too.

Thanks, I got my usb external HDD storage to work.

What I did, I compiled my kernel (2.4.20) with Knoppix's config file (to get the same modules and system). I only added kernel option for devfs and auto mount. After boot, run "modprobe *"
Device sda1 is in AL: /dev/sd/c1b0t0u0p1

The Knoppix's kernel config file is designed for hardware detect. Its good to use as a base when compiling for external hardwares. Here is the file:

For my work trying to make a hardware detect package for AL (this topic gave me a hope to succeed), how do you create a link file in /dev (example: /dev/sda1 --> /dev/sd/c1b0t0u0p1) same as current hda1 is installed at the boot? The Knoppix's hwd package I am modifying, may need to use common device names.

Untag old device names in /etc/devfsd.conf

REGISTER .* MKOLDCOMPAT
UNREGISTER .* RMOLDCOMPAT

Load usb modules (if not compiled in kernel):

modprobe usb-uhci
modprobe usb-storage

HOWTO-devfsd setup

The default /etc/devfsd.conf installed by devfsd contains some comments to get people started, but it's a bit limited. Here's a commented devfsd.conf with some additional setups for alsa, cd burning and other stuff, for further information on what you can do with devfsd.conf, see the devfsd manpage:

 
# Sample /etc/devfsd.conf configuration file.

# Enable module autoloading.
