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

sd 33:0:0:0: Attached scsi generic sg2 type 0
sd 33:0:0:0: [sdb] Attached SCSI removable disk
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?
