Ethernet over USB connectivity
SVedurumudi
Does any distro support usbnet (Ethernet using USB for the PHY
layer)? The Linux kernel does support it, I know. I ran the Android
build today but it doesn't seem to use usbnet. Curious if Angstrom
supports it.

Angstrom has usbnet supported. You can enable by configuring the
kernel with following options
Device Driver
* USB Support [y]
* Inventra Highspeed Dual Role Controller (TI, ADI, ...) [y]
* Driver Mode (Both host and peripheral: USB OTG (On The Go)
Device
* USB Gadget Support [y]
* USB Gadget Drivers (Ethernet Gadget (With CDC Ethernet
Support)) [y]
* RNDIS Support [y]

I have setup the OE environment following Koens write-up and also
created the images successfully, but I am unable to locate where I need
to make these changes. The defconfig file inside
OE/openembedded/recipes/linux/linux-2.6.29/tosa (which I believe is the
config file for the kernel since the boot messages show 2.6.29 as the
kernel in use), already seems to enable USBNet and RNDIS as evident from
the following lines. Also, I could not find any entry related to
Inventra. Please help me locate the exact file that needs to be changed.
#USB Network Adapters
CONFIG_USB_USBNET=m

You can change the .config file located at
OE/openembedded/recipes/linux/linux-2.6.29/

Did you try running dhclient (with sudo)?
And, are you sure your DHCP server works?

I also have 2 of them and check it out:
eth1: register 'dm9601' at usb-0000:00:1d.1-1, Davicom DM9601 USB Ethernet
I just run dhclient and works fine.

Maybe there's something wrong with them because they work fine on my
desktop running Ubuntu 9.10.
Are they even detected at all?

couldn't find it anywhere in the ${OETREE}and its subdirectories) . The
only thing under the linux-2.6.29/ folder is the tosa folder which
contains two patch files and one defconfig file.
Anywhere else?

Now, inside this defconfig, I see that USBNet is configured to be a
module rather than a built-in driver. Is that why USBNet does not come
up by default, in which case I have two questions:
1. How do I load the module (the command 'ifconfig usb0 up' does not
seem to load it)
2. I am assuming bitbake will recompile only the kernel (to include the
module) and leave the others untouched (so my compile time is small).
Please confirm.
Regards,
Sri.

defconfig is what you're looking for. The recipe installs it as '.config'
before building.

openembedded/recipe/linux/linux-2.6.29/tosa/ folder and issued the commands:
bitbake base-image
bitbake console-image x11-image
The process took just about 5-10 minutes and I'm sure the kernel did not
get re-compiled. How do I get this going?

If you want to compile kernel for Beagleboard you issue the command:
bitbake linux-omap
recompile:
bitbake -c rebuild linux-omap
delete kernel:
bitbake -c clean linux-omap
no Tosa at all!

not linux-omap, but virtual/kernel
vritual/kernel will always point to the correct kernel. And if you build it it will say at the start which files it's going to use so you can use that to find the defconfig.

What is incorrect with linux-omap? All files are listed in the respective bb file, including the defconfig. Aren't both these methods produce the same result?

They might, but the new 2.6.32 kernel in the feeds and on the website isn't built from linux-omap, so your instructions are wrong for that. If you build a kernel, use virtual/kernel then you can never go wrong.

Here is the defconfig file being used http://pastebin.com/P1mCsZ3t
But, I dont see the Inventra Highspeed Dual Role Controller in it.
Also, USBNet and RNDIS are enabled.
Still, I don't seen to get the USBNet functionality when I connect my
host to the BB. Any help here?

Sri.
