ath9k_htc fails with "Target is unresponsive"

ath9k_htc fails with "Target is unresponsive"

[David Madore]

Hi,

(I'm aware that the following might be more of a USB problem than a
Wireless problem, but I guess I need someone wiser than me to
translate the problem in terms that can be submitted to wherever Linux
USB problems should be submitted.)

I have an Atheros AR9271-based, TP-LINK model TL-WN422G USB wireless
dongle (USB id 0cf3:1006; full output of lsusb -v is copied at
bottom), which I'm trying to use with ath9k_htc from kernel version
3.2.12.  For what it's worth, the host system is an ARM-based Marvell
DreamPlug (the USB host adapter is orion-ehci; incidentally, the whole
point of using this dongle was that the Marvell SD8787 is unsupported
in master mode).

Initially, the dongle works.  But after a system reset, ath9k_htc
fails to load the firmware with a "Target is unresponsive" error, and
it becomes impossible to do anything unless I physically unplug and
replug the dongle.  (Unfortunately for me, this operation is not
acceptable, and having to do this makes the whole darn thing
completely useless.)

Here's what ath_9k says when it fails to initialize the dongle:

And here's what it says when it suceeds:

I also tried resetting the device with the usbreset program found at
<URL:
http://cpansearch.perl.org/src/DPAVLIN/Biblio-RFID-0.03/examples/usbreset.c
 >, but it does not suffice (in fact, using it produced the "failed"
log reproduced above).  Any suggestions on performing a deeper USB
reset (one that would be equivalent to unplugging and replugging the
dongle) would be welcome: the comments in the program mentioned above
suggest writing to /sys/bus/usb/devices/${id}/power/state but this no
longer exists and I was unable to find a replacement.

Any suggestions on debugging the problem, or finding a way to make the
thing not completely useless, would be very welcome.

Other than that, if someone can suggest a USB wireless dongle model
which is fully supported under Linux (including master mode) and does
not have this kind of problem, I'd be very grateful.

Lastly here is the output of "lsusb -v" for the device:

Re: ath9k_htc fails with "Target is unresponsive"

[Adrian Chadd]

Hi
,
Are you sure this isn't partially a USB controller/initialisation problem?

What's the exact combination that works/fails?

* power on boot with the dongle plugged in;
* reset pins shorted with the dongle plugged in;
* "reboot" from a running system with the dongle plugged in;

.. then repeat the above with the dongle unplugged during system
POST/boot, then plug it in once everything has initialised to
multi-user mode?

Could be.  I wish I knew how to be sure.  If it helps, I tried putting
the dongle behind a USB switch, which made no difference whatsoever.

Works.

The reset button on the box doesn't work.  If I reset through the JTAG
interface, the Wifi dongle fails to work.

Fails.

Plugging the dongle always makes it work, no matter how the system was
initialized.

Or, to summarize all of this: the dongle works if and only if
ath9k_htc is initializing it for the very first time since it was
physically plugged in or powered on.  No reset, USB reset or software
reset of any kind seems to help.

More accurately: the dongle fails to work if and only if, since it was
last plugged in, there has been a reboot (=anything short of a full
power cycle) after it has been initialized by ath9k_htc.

Unloading and reloading the kernel modules does not cause a failure
(but neither does it solve the problem).  Rebooting[#] the machine
causes the problem if and only if ath9k_htc has been loaded prior to
reboot (even if there have been other intermediate reboots).  Powering
the machine down, or unplugging the dongle, are the only way I've
found of restoring a sane state: no lesser kind of USB reset has
worked.

[#] I should try kexec, but I haven't been able to get it to work.

I'm willing to run any other experience which might elucidate things,
of course.

Re: ath9k_htc fails with "Target is unresponsive"

[Adrian Chadd]

Hi,

That sounds like the USB code isn't doing a full reset of the hardware.

What about seeing if the SoC or controller has some form of cold USB
device reset and make sure that's being done at device driver attach
time?

Thanks,



Adrian

Can you compile the driver/kernel with debugging enabled [1] ?
Then, load the driver with the module parameter 'debug=0x8701' and post the
kernel log here (a full run - load, use, reboot, load). Thanks.

OK, now I've discovered it's a bit more complicated than that: what
causes the dongle to fail is the following combination of events:

* the ath9k_htc module is inserted,

* the wlan0 device is NOT brought up,

* system reboot.

If, however, wlan0 is brought up before reboot, then the dongle is
still fine after reboot.

In other words: loading the module seems to place the dongle in a bad
state that goes away after ifconfig up (but not by removing the
modules), and if a reboot happens while the dongle is in that bad
state, it will fail permanently.

So following your suggestion

> Can you compile the driver/kernel with debugging enabled [1] ?

I produced a kernel log for the following sequence of events (the
numbers refer to the line numbers in the following log):

* plug in dongle (1-3), insert modules (4-78), bring wlan0 interface
  up (79-113), bring wlan0 interface down (114-127), remove modules
  (128-131), reboot (132-312; the dongle still works),

* insert modules again (313-386), now remove modules without ever
  using the interface (387-391), reboot (392-573),

* insert modules a third time, now they fail (574-580).

The lines marked "[U]" in the log are comments describing what I'm

Right, there's a difference here, a 'reboot' of the card is done only when
if the interface is brought up. The device status from the USB subsystem
is used to handle this - it works on x86.

On your platform, I think that a full reboot is required even when doing just
a simple load/unload cycle. I'll come up with a patch to test this.

Thanks for the detailed log.

Hi Sujith,
I seem to running into this same issue, mine is that the driver emits the
"Target unresponsive" error if the unit is powered-up with the TL-WN721N plugged
in already. I think my issue is that the USB subsytem event is not recieved by
the atk9k_htc driver, and therefore the hardware is not reset.

Has this ben fixed already? Can you give me the commit sha1 in wireless-testing?
I am using compat-wireless, so I am lagging master a bit.

If not, can you point me at where in the driver code the reset happens? Maybe I
can come up with a patch.

You can play around with the function ath9k_hif_usb_disconnect() in
drivers/net/wireless/ath/ath9k/hif_usb.c which has the deinit/reboot code. :)
