usb device not showing up

usb device not showing up

[Norbert Preining]

Hi all,

(please Cc)

I have the following problem with a disappearing or better not appearing
device: My Sony Vaio VGN-Z11 laptop contains a HSDPA modem:
	USB: Bus 004 Device 002: ID 0af0:6911 Option
which is very nicely supported by the hso kernel module (when using the
latest hso patches for the BUG).

Interestingly this device does disappear if I cold boot into linux.

So:
- First booting Vista, then RE-booting (not turning it off in the
  meantime) into linux gives me that device and everything works.

- Cold-booting into Linux and the device does not show up.


There were some suggestions I found on the internet that I should echo 1
to /sys/devices/platform/sony-acpi/wwanpower, which I could do and the
value could be read from it again, but it didn't make the USB device
show up.

Is there any way to activate this device other than always going into
Vista first?

Is there a way to save some settings of this device after a reboot (so
in a functional state) and restoring that later on?

I am currently running 2.6.28-rc3 with Mattia Dongili's latest sony-acpi
patches sent to the acpi ML, but had the same problems with -rc2 and
2.6.27, without additional patches.

Please let me know if I can provide further information, I will also
happily hack my kernel to get this device working out of the box.

Thanks a lot and all the best

Norbert

What happens if you leave the modem turned off until after Linux is 
running?  If it does not show up then a usbmon trace would be helpful 
(see Documentation/usb/usbmon.txt for instructions).

I can run usbmon, but I am not sure what you mean with "leave the modem
turned off until after Linux is running".

If I start from turned off state of the laptop and boot into linux the
device is not showing up. Is it that state you are interested in getting
the usbmon output?

Best wishes

I must have misunderstood your earlier message, where you wrote:

By "it", did you mean the laptop or the modem?

No.  I'm interested in seeing the usbmon output for when the modem is
first detected by the USB subsystem.  During a normal boot this will 
happen before you can start usbmon.

If you can't boot with the modem off, then try this instead: Unload 
ehci-hcd, uhci-hcd, and ohci-hcd, then start up usbmon (copy the 0u 
file) and reload whichever driver the modem attaches to.

I meant: 
- first booting vista, then re-booting ... the device shows up (and is
  functional)

- booting from off state the device does not show up and cannot be
  switched on using /sys/devices/platform/sony-laptop/wwanpower
  (although the behaviour that it can be switched on using the above
  sysfs file is documented)

Ok, I will recompile my kernel with USB as modules and do the above. Is
there a way to tell the kernel not to load any device drivers/modules
(probably overriding modprobe in some way)?

You can add entries to /etc/modprobe.d/blacklist.  But for temporary 
testing, it might be easiest simply to rename the module files 
themselves (under /lib/modules/.../kernel/drivers/usb/host) so that the 
hotplug system can't find them.

Ok, here it is. Booted with init=/bin/bash, no modules loaded, mounted
/sys and debugfs, cat u0 > usbmon.txt. Then load uhci-hcd, then load hso
modules.

Finally, kill the cat process.

Output is the attached usmon.txt file.

Well, this is a little odd.  The trace shows the modem was detected and
enumerated correctly.  But there's nothing corresponding to when you
loaded the hso driver.  In fact, there's nothing after uhci-hcd 
finished starting up and the unconnected root hubs were suspended.

Did you look in /proc/bus/usb/devices at this point?  And what about
the files in /sys/bus/usb/drivers/hso/?

This suggests the problem may lie in the hso driver itself, or in a
failure to bind the driver to the device.

Strange. I will redo the thing and see if something changes the second
time. I am quite sure I loaded hsom but of course without udev running
(init=/bin/bash) no devices were created.

I don't remember, will redo it.

Well, the point is that under these circumstances, as I explained,
*there*is*no*problem*, I can use the device without any problems.

Only when I turn of the computer and turn it on again the device simply
does not show up in the usb system.

Best wishes

Oh.  Well, you should rerun the test under circumstances in which there 
_is_ a problem.

Okay, then do the test that way.

Here it is. Sequence of events:
- turn off the laptop, physically
- turn it on
- boot in to linux with modular usb and init=/bin/bash
- mount /proc, /sys, /sys/kernel/debug
- modprobe usbmon (file /sys/kernel/debug/usbmon/{0s,0u} are present)
- start some getty to have more terminals, mount / rw

- cat /sys/kernel/debug/usbmon/0u > usbmon-bad.txt
- modprobe uhci-hcd
- modprobe hso

The device does not show up in /proc/bus/usb/devices (mounted before
probing and debugging), only bus 4 hub is there.

/sys/bus/usb/drivers/hso/ shows
	bind  module  new_id  uevent  unbind

- sync
- cat process

Outcome is the attached usbmon-bad.txt

This is the one where the device does not show up.

Best wishes

Okay.  In the earlier (working) test, the modem showed up on bus 4, not
bus 2.  Not that it matters much -- the modem didn't show up at all in
this test, on any bus.  Its USB interface seems to be electrically
disconnected or turned off.

Evidently the system needs to do something to tell the modem that it
should start working, but I have no idea what that would be.  It's not 
a USB issue; as far as USB is concerned the device just isn't there at 
all.  Maybe the hso developers will have some idea.  Or maybe it's 
controlled by a setting in your laptop's BIOS.

Interestingly, this trace appears to be missing some events.  There's a
gap between timestamps 4284549076 and 4284645743 (the timestamps are in
the second column) where we should see the initialization of bus 5 and
bus 6.  Instead there's a 100-ms delay in which nothing happens,
followed later on by the second initialization phase for those two
buses.

I have to wonder...  Did you remove any part of the trace?  Did usbmon 
malfunction?  Did parts of the initialization for those two buses 
really get skipped (I can't imagine how)?

Pete, any ideas?

Sorry, it is always bus 4, i meant interface (or how do you call it) 2,
bus id 004:002

Right.

Ok, if it is not an usb issue, I guess I have to hope for some fix in
sony-laptop module.

No. I sent you the output as it was saved on my hard disk. No editing
involved.

No idea. I can redo any tests you want, but I can guarantee that I
didn't tinker with the usbmon-bad.txt file itself, it was created with
	cat .../0u > usbmon-bad.txt

It is possible for usbmon to lose events. There's a counter to
monitor it, in 0s file. I do not commonly run across such problems,
but it can happen. If it's a problem, one can try to bump the limits
way higher, if RAM allows.

Yes, okay.  That's bus 4, address 2.

I hope it works out.

It must be like Pete said: Some events just got lost because not enough
memory was allocated to usbmon.  Fortunately those missing events had
nothing to do with the hso problem.
