I want to compile a firmware with support for the usbserial kernel module, and compile a kmod-usb-serial ipkg.
I've downloaded the buildroot tarball and compiled OpenWRT once successfully. I've had a close look at all the various makefiles, control files and Config.in files.

To do what I want to do I think I need to add appropriate entries for usbserial and associated modules to these files:
openwrt/target/linux/linux-2.4/Makefile
openwrt/target/linux/Config.in

And I need to create:
openwrt/target/linux/control/kmod-usb-serial.control

The way I understand it, the makefile will reference the module source code files contained in the /openwrt/dl/linux-2.4.30.tar.bz2 tarball that was downloaded the first time I compiled OpenWRT.

Basically I want to know - am I on the right track? I haven't tried compiling it yet, I will do so shortly. I'm just after some feedback - and am wondering if there's anything I missed.

If I get it right I will submit a patch

All right, you may also have to edit the kernel config in :
openwrt/target/linux/linux-2.4/config/

and enable the modules you want if they are not already.

Yeah, patches are always welcome !

Thanks for your contribution

Thanks Nico
I have now edited and created all the relevant files to create the usb-serial kmod packages.
I did a make and it came up with an error saying it could not find usbserial.o. This is because usbserial.c wasn't unpacked from the linux-2.4.30 tarball the last time I compiled because it wasn't needed. Is there a way to tell the main makefile to unpack the .c (and any other) files that are now needed?

In the end I just deleted the build_mipsel directory. I suppose I could have unpacked the files that were needed into the right place, but I thought I'd start again anyway.

Also, what's the preferred format of patches? I compiled the whiterussian-rc2 tarball once then copied the whole openwrt directory tree (calling it openwrt-mod). I am making my changes in openwrt-mod. Should I just go into the openwrt-mod directory and do a diff against the unchanged openwrt directory? Where should I do the diff? And what options should I pass to diff?

As I said in my previous post, you should edit the kernel config files found in ./target/linux/linux-2.4/config/

Here's a patch below for you to apply in your openwrt-mod directory with the following command :

# patch -p1 < openwrt-kconfig-usb_serial.patch

This patch will only enable the generic USB serial converter

I can also download it, if you prefer.

You can create your patch with the following command in the parent directory of your openwrt and openwrt-mod directories:

# diff -ruN openwrt/ openwrt-mod/ > a_self_exlpanatory_name_here.patch

Hope you'll find your way through

Thanks again Nico - I should have a nice patch for you shortly. I've compiled it successfully once with the usbserial kmod package. Now I want to add the other drivers - and I've hit the same minor snag again when I do a 'make'.
Here's the error:

rm -rf /usr/src/whiterussian_rc2/openwrt-mod/build_mipsel/linux-2.4-brcm/linux-modules/ipkg/usb-serial-belkin
mkdir -p /usr/src/whiterussian_rc2/openwrt-mod/build_mipsel/linux-2.4-brcm/linux-modules/ipkg/usb-serial-belkin/lib/modules/2.4.30

echo "Depends: kernel (2.4.30-brcm-2), kmod-usb-serial-belkin" >> /usr/src/whiterussian_rc2/openwrt-mod/build_mipsel/linux-2.4-brcm/linux-modules/ipkg/usb-serial-belkin/CONTROL/control
cp  /usr/src/whiterussian_rc2/openwrt-mod/build_mipsel/linux-2.4-brcm/modules/lib/modules/2.4.30/kernel/drivers/usb/belkin_sa.o  /usr/src/whiterussian_rc2/openwrt-mod/build_mipsel/linux-2.4-brcm/linux-modules/ipkg/usb-serial-belkin/lib/modules/2.4.30
cp: cannot stat `/usr/src/whiterussian_rc2/openwrt-mod/build_mipsel/linux-2.4-brcm/modules/lib/modules/2.4.30/kernel/drivers/usb/belkin_sa.o': No such file or directory
make[3]: *** [/usr/src/whiterussian_rc2/openwrt-mod/bin/packages/kmod-usb-serial-belkin_2.4.30-brcm-2_mipsel.ipk] Error 1

The thing is, belkin_sa.o is there, but it is in

build_mipsel/linux-2.4-brcm/modules/lib/modules/2.4.30/kernel/drivers/usb/serial/belkin_sa.o

and the makefile is looking for it in

build_mipsel/linux-2.4-brcm/modules/lib/modules/2.4.30/kernel/drivers/usb/belkin_sa.o

The same thing happened to me when I did the 'make' to include kmod-usb-serial - it was looking in the wrong place - but when I deleted the whole build_mipsel directory tree it started from scratch and everything worked - but obviously this is an inelegant fix and takes more time because everything has to be recompiled.

Update: OK typo on my part - I was referencing the wrong place in target/linux/linux-2.4/Makefile <sheepish grin>. She's compiling again now.

It adds menuconfig items, kernel options, control files and compiles the kmod packages for most of the usb-serial adaptors supported by Linux.

I did the diff against the target/ directories under my unmodified openwrt directory and my modified openwrt-mod directory from the WhiteRussian_RC2 tarball.

I've tested it with with a PL2303-style usb-serial converter and it works. The adaptors appear as /dev/usb/tts/0, /dev/usb/tts/1, etc. I can read and write to/from them using a null-modem cable attached to my PC. Setserial doesn't work with it, and I can't get a shell by specifying "usb/tts/0::askfirst:/bin/ash --login" in /etc/inittab, but that's a whole other story. We've only just begun...

I've put the usb-serial kmod packages online. I'm not sure how useful they will be to people who haven't compiled their firmware with the correct kernel options, but I thought I'd put them up anyway.

My stupid web host doesn't allow virtual directory listing, and I can't be bothered listing every single module, so here are the main ones:

kmod-usb-serial_2.4.30-brcm-2_mipsel.ipk
kmod-usb-serial-pl2303_2.4.30-brcm-2_mipsel.ipk

The others are listed here:

Thanks for doing the work.
I started doing the same a few days ago.
However, I have a converter with a FTDI chip, which you didn't include.
I added this one and rearranged some options (usb-serial first, usb-multi-serial next, everything else at the ende)

attached is a patch against today's cvs
