Can't connect in Linux - usb0 interface never shows up

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Start wired-tether
2. Plug phone into usb port of computer
3. sudo ifconfig

What is the expected output? What do you see instead?

Instead of seeing usb0 listed as an available interface I only see wlan0 
which is my wireless card.

What version of the product are you using? On what operating system?

I'm using wired-tether 1.2 on a Sprint Hero running DamageControl 1.0 ROM, 
which is an Android 2.1 ROM.

Please provide any additional information below.

I'm using arch linux, and I've also tried using xubuntu with the same 
result.  I believe the rndis module is loaded.  I've added "rndis_host" to 
my modules list in rc.conf.  I've also done modprobe rndis_host and then 
plugged the phone in.  Still no usb0 interface.

Here is my dmesg output when I plug the phone in.

You see the SCSI device which means you did not enable the tethering properly.

My Hero shows the SCSI interface when not sharing the connection and as soon as
sharing turns on, the SCSI interface disappears and an RNDIS interface appears.

As an addition: I am talking about the stock tether functionality of the Hero, I
assume this goes for all wired tethering techniques (as the phone can only play 
one
role at a time). Ergo: seeing SCSI is bad.

I get a similar dmesg when I connect the USB cable:

It complains about only finding 2 interface descriptors while it was expecting 
4 from
the configuration descriptor. Then it also says that duplicate descriptors for
interfaces 0 and 1 were found, and it is ignoring these.

Doing a "lsusb -v" shows the problem:

The first two interface descriptors (0 and 1) are there when wired tether is
disabled. The last two appear when wired tether is enabled. However, instead of
appearing as interface descriptors 2 and 3, it reuses 0 and 1, and linux thinks 
these
are duplicate descriptors and ignores them. I think the way to fix this is to 
find
out how many interfaces the phone is exposing without wireless tether, and 
increment
the interface descriptor numbers accordingly.

I get this problem with my Evo 4G. When I disabled usb storage and USB 
Debugging, the tethering app works.

It seems the program can't override the usb mass storage default.  Therefore 
windows can't load the rndis drivers.  Once the usb storage is disabled the Evo 
tethers fine.  A reboot is needed for usb storage to work again.

With htc tattoo, i cannot see usb0 interface in linux machine (which is still 
recognizing the phone as storage disk  ?) 
In linux -> output of dmesg

however i am able to see usb0 interface in phone (via adb shell).

Has anyone figured out how to resolve this issue? I'm still having the same 
problem on Epic 4G running RandomROM EI22 Thunderhawk.

As for the client, I'm using Linux Mint 11 x64 and a fresh install of Ubuntu 
11.10 x64, and I'm still stuck in scsi. I tried disabling USB Debug mode and 
rebooting (both phone and computer) with no luck.

It was working fine before with Mint, but I'm not sure which change made it 
stop working. I'm pretty sure this is a configuration issue with Linux, as I 
just tethered my phone to my Windows desktop without issue last night. Also, 
using a terminal emulator, I ran ifconfig and also noticed the usb0 interface 
in the phone.

Suggestions/solution?
