Hello!
$ uname -a
Linux 2.6.32-5-amd64 #1 SMP Thu Nov 3 03:41:26 UTC 2011 x86_64 GNU/Linux
$ cat /etc/debian_version

$ lsusb|grep -i asix
Bus 004 Device 014: ID 0b95:772b ASIX Electronics Corp.
1) Driver asix.c from linux-3.2-rc6.
asix.c little modified for compiling in 2.6.32 . Diff is at the end of message.

Hi Igor!
The goal(s) of your email/patch aren't 100% clear to me.
Is the main goal to provide a backport of 3.2-rc6 asix.c driver to
pre-2.6.35 kernels?
(If so - thanks! I'm sure someone can make use of it.)
Why the comparison to ASIX v4.2.0 driver?
cheers,
grant

What you're seeing isn't strange, it depends upon what ethernet devices were
visible when you installed your machine.
'udev' in userspace remembers the mappings from ethernet addresses to
device names, and renames devices as the system comes up to what it
first saw them as, based upon the MAC address.
So one possibility is that there were 2 other ethernet or wireless devices
in your system at install time, so the one that the ASIX device got was
'eth2'.
Therefore that is the device name it will have until you tell 'udev' to
do otherwise.

Dear David,
Thank you very much!
It helps.
Sorry for my stupidity.

I was told to buy a lot of these adapters, but at first to test them. In
the debian stable there is old driver which does not see these adapters.
Driver from the vendor looks suspicious. I thought it better to get
driver from the current linux-3.2-rc6. But by mistake I thought I found
a bug, and decided to tell you. Time running out, and I cannot think
anything better than write to this mailing list. The next time I'll be
more careful, I will think ten times before worry developers. Sorry!
