We would like to see our Atheros 802.11n USB Linux driver upstream
however we need help with this so we are releasing our Atheros 11n USB
Otus Linux driver under the ISC to the community. The goal is to work
with the community to help move this forward upstream. We are hoping
for community help and leadership on this (*cough*).
In the meantime users should be able to use this driver and patches
are welcomed to add newer wireless extension support so users on newer
kernels can get their devices working. The focus should be upstream
though :)
Anyway, some more details.
Supported hardware:
Atheros 802.11n hardware: UB81, UB82, UB83
Requirements:
Kernel 2.4 - 2.6.24
Get the driver:
git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/otus.git
Features supported:
* IEEE standard compliance
* IEEE 802.11a/b/g
* IEEE 802.11h, 802.11d
* IEEE 80211i
* IEEE Draft 2.0 802.11n
* Ad Hoc
join (2.4GHz, 5GHz if SKU allows), create (2.4GHz , 5GHz if SKU allows)
Adhoc security: WEP
* Security
Authentication: WPA/WPA2 (Personal / Enterprise),
802.1x Encryption: none, AES, TKIP, WEP40, WEP104
wpa_supplicant otus driver:
This driver requires its own supplicant driver for wpa_supplicant
0.4.8. For your convenience you can find the tarball here:

Ok, I've now added it to the staging tree and will forward it on to
Linus. After it gets there you can probably drop the git tree.

You might want to link to this off of the "main" drivers page as well.

We have set up a mailing list for the new driver:
[email protected].
No subscription required. However, the first post from unsubscribed users
will be held back for moderation (which usually takes 24 to 48h) to
protect the list from spam. The delay can be avoided by subscribing [1].
Please contact me if anything goes wrong with the list.

Binary firmware for a device does make the driver still "open source"
except for how some people intrepret it.
It is legal from a kernel standpoint though, and so it is fine to add to
the kernel as-is.

Yes they should, patches gladly accepted :)

If someone can tell me what device this is for, I can try to go buy it
so that I can verify changes I make don't drasticly break things.
I'll go try to get this tree into a buildable state and put it into
staging tonight.

I've tested the TL-WN821N (it's the cheapest N USB I think) with a
generic 802.11g router (WPA enabled) on 2.6.24.7, 2.6.27.4 and
2.6.28-rc2.

I'll test the for-upstream branch soon.

I'd guess the

should be in this list, too.
I don't own one (yet), but the Windows driver contains:

...
4de20 Atheros OTUS Wireless Network Adapter
...
Could some owner please confirm the chipset of this stick?

Yeah, it works up to 2.6.24.

That's the thing it needs Wireless Extension support for >= 2.6.24 so
that needs to be done. I can try to do it but first comes ath9k, hence
why we released it to engage with the community on adding that and to
eventually push it upstream.

Yeah so the purpose of the git tree is to collect patches to allow users
to use it with >= 2.6.24, all other focus should be on an in-kernel
driver.

This is now fixed on the master branch, also the branch "for-upstream"
does a lot of cleanup I thought you may like before stuffing it into
staging like removing all KERNEL_VERSION checks, all wireless
extensions checks, some compile warnings, removal of compat, dos2unix,
use utf-8, etc. Unfortunately this still requires a specific version
of wpa_supplicant but it seems it works. Not sure what bars you have
for staging at this point.
Will you take this in, and expect patches for fixing it to use
standard wext and also report standard wireless statistic (yeap, this
is not there yet either).
Joey is one user which reported the driver working now with the
compile fixes for newer kernels for 2.6.28-rc2 using the specific
version of wpa_supplicant for it.
Joey can you test the for-upstream branch on otus git?

So we have a page for this now:
http://wireless.kernel.org/en/users/Drivers/otus
Init you can find a list of devices. Let me just paste what we have
there now:
Dlink
* DWA-160A1
Netgear
* WNDA3100
* WN111v2
TP-Link
* TL-WN821N
AVM
* FRITZ!WLAN N USB Stick (USB ID 0x57c, 0x8401)
> I'll go try to get this tree into a buildable state and put it into

Thanks! BTW if you add a kconfig option for it please point users with
this info:
This driver requires its own supplicant driver for
wpa_supplicant 0.4.8. For your convenience you can find
the tarball here:
http://www.kernel.org/pub/linux/kernel/people/mcgrof/otus/wpa_supplicant-0.4.8_otus.tar.bz2
Before compiling wpa_supplicant, ensure your .config has atleast the
following
CONFIG_WIRELESS_EXTENSION=y
CONFIG_EAP_WSC=y
CONFIG_WSC_IE=y
CONFIG_DRIVER_WEXT=y
CONFIG_DRIVER_OTUS=y
After a successful compile, you can use the device with wpa_supplicant
as follows:
wpa_supplicant -Dotus -i <atheros device from ifconfig> -c /path/to/wpa_supplicant.conf -d

I was a bit disappointed to find binary-only firmware inside the
driver (HalPlus/OTUS_FB50/{hpfwbu,hpfwuinit}.c which is downloaded
into the device during startup (initially thought this to be a
complete OpenSource driver :-(
Unless the attitude towards binary chunks inside the Linux kernel
have changed, I guess these should be moved into userspace using the
firmware_class driver to access it.

I'll grab this and put it in drivers/staging/ so it gets some users and

Ok, it seems to need some basic work to merely build properly on
"modern" kernel versions.
So, how should we do this if I want to move it into staging? Can I just
take a snapshot of what you have in this repo, move it in-kernel, fix
the build errors and apply that patch (as your contribution of course)?
Then future development can go off of the in-kernel version? Or do you
plan to keep this git tree active somehow?
thanks,
greg k-h
