Problem with Telefonica USB wifi adapter

Hi,
I'm trying to use a wifi usb device in Kubuntu Karmic (9.10). Info of
the hardware & system:
* lsusb ID 083a:e501 Accton Technology Corp. ZD1211B
* dmesg: zd1211rw 2-2:1.0: zd1211 chip 083a:e501 v4810 high 00-1a-2a AL223
* uname -a: 2.6.31-17-generic #54-Ubuntu SMP Thu Dec 10 17:01:44 UTC
2009 x86_64 GNU/Linux

Following your instructions, I do:
    modprobe zd1211rw
    echo "083a e501 FFFFFFFF FFFFFFFF 0 0
1">/sys/bus/usb/drivers/zd1211rw/new_id
and a new interface wlan1 appears. But:

* It doesn't associate to the AP:
  iwconfig essid MYESSID key s:MYASCIIKEY

* It's unable to scan:
  iwlist wlan1 scan
  wlan1     Interface doesn't support scanning : Device or resource busy

Apart from this, I'm using another PCI wifi card, wlan0, with ath5k
module and it goes ok.
I'll try to use ndiswrapper, but I prefer the "native" mode so, any
help will be appreciated; write me if you want me to do any test.

    Thanks a lot in advance.

Re: Problem with Telefonica USB wifi adapter

Hmm, do you really need the echo part? current wireless-testing/compat-wireless already have the 
083a:e501 id.

Well, I didn't find that ID in http://linuxwireless.org/en/users/Devices/USB.
Also if I do
   modinfo zd1211rw | grep -i 083a
it doesn't appear. Maybe my module is a little bit old?
   modinfo zd1211rw
gives:

Re: Problem with Telefonica USB wifi adapter

Apparently it was me who added that ID to wireless-testing 6 months ago, and it entered mainline kernel at
2.6.32. (not in 2.6.31). Sorry I don't have data on 2.6.31.x, but you probably should just upgrade to
2.6.32+ .

BTW, wiki is't always up to date... but in any case, the id is in 2.6.32 for certain.

Re: AP mode for zd1211 won't build on 2.6.31.6

You obviously did not read any of the archive postings, nor look at the web site in details. The
vendor-derived driver has been defunc for a while; most people use the in-kernel rw driver, others use the
vendor driver + my patchset.

Grep the latest vendor tar ball, 

http://www.kernel.org/pub/linux/kernel/people/mcgrof/zd1211/

then grab the corresponding patch set:
http://htl10.users.sourceforge.net/patchsets/

[report] the "NEC Aterm WL54GU" usb wireless stick works well.

Hi,

I'm using the usb wireless stick, "PA-WL54GU," and it is working good.
I just modified the zd_usb.c file with the following line.
	{ USB_DEVICE(0x0409, 0x0248), .driver_info = DEVICE_ZD1211B  },

The brand and retail product name
	NEC, Aterm PA-WL54GU
The USB ID's (duh)
	ID 0409:0248
The chip ID string
	zd1211rw 1-1:1.0: zd1211b chip 0409:0248 v4810 high 00-1b-8b AL2230S_RF pa0 g--N-
The FCC ID
	unknown

Your work is very helpful, thanks a lot.

Re: AP mode for zd1211 won't build on 2.6.31.6

Executive summary: thanks for the links. I built the driver but master mode 
doesn't look supported still:
gandalfthegrey:/usr/src/zd1211# iwconfig ath1 mode master
Error for wireless request "Set Mode" (8B06) :
    SET failed on device ath1 ; Invalid argument.

Back to your mail:

Well, I did spend about 1H looking, but:
1) which web site?
Isn't http://linuxwireless.org/en/users/Drivers/zd1211rw the canonical
site?
If so, unless I read wrong it states nothing of the site you gave below.

2) I searched all archives I could find with "zd1211rw master mode"
on google and it brought me to this list, although I didn't find any
posts I should have found you are referring to.

Even http://lwn.net/Articles/186311/ points back to
http://zd1211.ath.cx/wiki/DriverRewrite which brings one here
http://sourceforge.net/projects/zd1211/develop.

Is there a way to seed google with the right answer and get it on
http://linuxwireless.org/en/users/Drivers/zd1211rw?

Re: AP mode for zd1211 won't build on 2.6.31.6

Interesting - here used to be some info explaining the three at :

http://zd1211.wiki.sourceforge.net/

but now that's gone and get re--directed back to the download site.

You need to ifconfig up first. Nothing works before ifconfig up.

Re: AP mode for zd1211 won't build on 2.6.31.6

Thanks for your replies and pointer to the code that builds.
Unfortunately, after I bring it up, it doesn't seem reliable enough to
allow connections.

In a nutshell, my phones see the AP. Sometimes I am able to connect to
it but not get an IP. Very rarely I get an IP, and my machine usually
ends up crashing some time around that.

One noticeable thing is that 
Tx excessive retries
in iwconfig shows a few hundred errors per second.

Is the AP code working and stable for you?

Below is the code I wrote:

#!/bin/bash

IF=ath1
