The following patch against -current enables the Samsung Galaxy S
Android device (Samsung Captivate with AT&T) to be be used for USB
tethering.
With or without this patch, the device can still act as a modem and
can be used with PPP. With this patch, the device can be used as an IP
router over USB the same way that the Mobile AP mode works.
A new USB device shows up when "USB tethering" is enabled on the
Galaxy S.
I was able to obtain an IP address via DHCP from the Galaxy S and ping
the device.
Dmesg snippet without the patch...
