Hi!

I am trying to tether my HTC Hero (Android 2.1, not rooted, and without any sort of tethering app) into my gentoo laptop, with kernel 2.6.34-gentoo-r12. Yes, old kernel, I know.

The problem is that the interface usb0 is not showing up.

I have followed the following links:
http://wiki.gentoo.org/wiki/Android_USB_Tethering
https://forums.gentoo.org/viewtopic-t-843255-postdays-0-postorder-asc-start-0.html
https://forums.gentoo.org/viewtopic-t-901542.html
http://tomatousb.org/forum/t-259025/usb-android-tethering-modules
http://www.linuxquestions.org/questions/gentoo-87/tethering-displays-sit0-interface-913105/

Still, I can't seem to make this work.

I can tell, from everywhere on the internet, that I should see a line like this on dmesg:
Code:
[250278.078911] rndis_host 2-1.2:1.0: usb0: register 'rndis_host' at usb-0000:00:1d.0-1.2, RNDIS device

and indeed, when I tried it on a Debian Squeeze machine, that's the output I got, and the interface usb0 showed up.

However, on my gentoo box, this is the output of dmesg:
Code:

(MAC address and serial number masked)
The lines from rndis_host and usbcore are what matters the most, here.


The phone has no problem, or it wouldn't work on Debian. The problem has to be in my configuration.
Debian Squeeze's kernel is 2.6.32. It's the vanilla kernel from Debian.
My gentoo kernel was compiled by me.
I activated every module recommended in the above links:
Code:

CONFIG_USB_NET_RNDIS_WLAN=m
CONFIG_USB_NET_RNDIS_HOST=m
CONFIG_USB_ETH=m
CONFIG_USB_ETH_RNDIS=y
CONFIG_USB_ETH_EEM=y
CONFIG_USB_GADGET=m
CONFIG_USB_SERIAL=m
CONFIG_USB_SERIAL_OPTION=m


I rebooted, I had to modprobe the modules manually because they didn't fire up when I connected the phone, and even then, they did nothing.

I don't know how at a deeper level what it is in the kernel that makes this happen:
Code:
[250278.078911] rndis_host 2-1.2:1.0: usb0: register 'rndis_host' at usb-0000:00:1d.0-1.2, RNDIS device, ##:##:##:##:##:##

what is it in the kernel that calls rndis_host? Whatever it is, it isn't happening in my gentoo machine, and I don't know what to look for now.

I thought about udev, and this is the output of udevadm monitor, on

gentoo:
Code:

KERNEL[1353810927.830500] add      /devices/pci0000:00/0000:00:1d.7/usb2/2-3 (usb)

UDEV  [1353810440.097496] add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)
UDEV  [1353810440.104283] add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/net/usb0 (net)

(I can post more, but I think this is the relevant part)

I think this is enough information for someone who understands how things work at a deeper level. Unfortunately, I can't seem to move on from here by myself anymore.

Thank you for your attention!
