ethernet over usb otg on beagleboard -- no "Auto usb0" on the host?

when I type dmesg on beagleboard, it shows below message. At the end, there is a line "ADDRCONF(NETDEV_UP): usb0: link is not ready". Does it mean there is hardware link problem or usb function is not enabled?

It seems very easy from the Beagleboard web, but I have spent more than one week and still do not know how.

If any of you can help me, I will really appreciate.

Nobody replies? If anyone ever used the ethernet over usb on beagleboard, could you give me some suggestion?

Thanks.

You shouldn't need to solder anything. A standard USB cable should work. When you connect from the Beagleboard to your host PC do you see any usb interfaces on the host?

hi,

Thank you for your reply. I did not see any usb interfaces on the host. I have host Window Vista and Ubuntu on vmware. I did not see any prompts like "new device found", so I doubt I enable the USB gadget correctly. It is really strange.

If you make it work, could you tell me how you did it? which Angstrom image, file system etc. Thanks again.
