[Hu Haiqing]

Hi, Dear All:

I would like to insert a device to android phone through usb
interface . and hope the phone can access the device through tcp/ip
protocol. is it avaialble to me

The device is standard usb CDC device, in Ubuntu, I can see the ip
address use ifconfig command when I insert the device into the
computer.

Best Regards.

Hi,

Yes, USB net (host) driver is availailble for android, actually it is in linux kernel before.
On host side, you config kernel to support USB net (in Network configuration menu)
On device side, you config kernel to support USB gadget CDC ethernet (RNDIS) (in USB driver configuration menu)
configure ip by : ifconfig usb0 <ip_address>

Cheer,

While the usb net and usb host drivers are likely available in kernel
source, its worth pointing out that they aren't shipped in most
phones, so a new kernel (probably not just module) will need to be
compiled. Something will likely also be needed in sub-android linux-
level userspace to set it up.

Also most current phones don't supply usb bus power, so custom cabling
and another power source may be needed.

Hi,Chris
Thanks a lot,could you please give me more detail abou the two things.

1) What's will be needed in sub-android linuxlevel userspace to set
it up?

2) For the usb bus power, you mean that the usb device it's self (not
the phone) may need another power source?
I have a Radio device which is supplied the power via battery.
does it need another power source?

Best Regards.

For the first question look at how wifi is handled as an example. The
second depends on your usb peripheral. If you get a usb extension
cable and cut the power lead then plug it into a desktop pc through
that, you will find out.

I know this is a couple years old, but I'm wondering if someone could point me
in the right direction. I don't think my kernel has usbnet support already on
the phone. How would I go about compiling and loading a new kernel that does
have usbnet as Chris mentioned? It's a Galaxy Nexus running Android 4.0.4 and
kernel 3.0.8.

Thanks,

Justin
