Getting USB to serial convertion modules on 13.37 installation DVD

June 14th, 2012 - 11:19 pm ET by Mike Keithley | Report spam
Hello group,

I want to install 13.37 on a netbook with USB ports. I need USB to serial
conversion so I can use my braille display, which has a RS232 port.

When I plug in my FTDI USB Serial Device, the system doesn't have the
modules to support it. How do I add these modules to the installation DVD?

This converters works fine on my 13.37 desktop box.

Thank you.

You might check permissions of the USB port, as ttyUSB0 or whatever, since
it may need write permissions to set the port up. I've often had to add suid
permissions to programs so they could manipulate the port or physically
change permissions of the port. Just a thought.

Modifying the installation disk initrd is rather easy. I haven't tried
13.37 myself, but use the following method on 13.1:

mkdir /tmp/initrd_src
cd /tmp/initrd_src
gzip -d < /mnt/cdrom/isolinux/initrd.img | cpio -i

The above command should be run as root if you want to preserve ownership
of the files in initrd. Once the initrd file system has been unpacked in
/tmp/initrd_src you will be able to add your module files or do any other
modifications. When you are done with your modifications, do the following
to create a new initrd image:

cd /tmp/initrd_src
find . | cpio -o -H newc | gzip > /tmp/initrd.img

You don't have to be root to create initrd.img. Once you have your new
initrd.img, add it to your installation directory for burning out to a new
installation DVD.

If you're happy with your desktop installation, you could clone it to the
laptop. One way to do this is booting with the Slackware installation
disc, setting up the hard drive and the network, and using rsync for the
copy.

While this ordinarily might be a good idea, remember that the OP
probably has limited vision (since he wants to use a Braille display),
if he isn't outright blind. Can you do this literally with your eyes
closed? Can everything necessary be done from the desktop PC? Pehaps
these are moot points if he can get assistance from a sighted person.

Also, it's quite possible that the desktop PC is 64-bit and the laptop
is 32-bit.
