[Bitpim-devel] linux debugging questions (really USB questions)

[Paul T. <bit...@st...>]

Roger (et al),

I'm trying to get 0.7test6 running on a Linux box.  I'm sorry, I have
little if any previous USB under Linux experience.

The environment:

Linux quemadura.shockwave.org 2.6.4-1-686-smp #1 SMP Sat Mar 13 21:05:54 EST 2004 i686 GNU/Linux

Debian testing/unstable

I've brought up bitpim.  I first tried to let it auto-find my LG VX6000
phone with no luck.  I figured libusb/usbscan was just confused?

The output of usbscan if run separately is nothing (nothing found).
I then tried /dev/usb/acm/0 as a hope of accessing the diagnostic port,
that failed with a BREW CRC error, so I assume that the particular port
I tried to access represents either the data port or some strange
composite port for the modem.

Traceback (most recent call last):

I saw your note about checking libusb against the kernel (since I am
running 2.6 and downgrading is not an option for me).  I ran the testusb
utility (as well as lsusb).  It appears to clearly be finding the ACM
device and a couple of bulk endpoints (?), but the bit about not reading
the vendor string seems like it might be an issue?  However I know that
we should just be looking for the IDs?

This could simply be that I don't know where to get access to the damn
thing in my /dev (devfs) tree.  Any suggestions as to what the right
major (and minor) numbers for the diag port device should be?  Then I
could just run a find command to figure out what debian called it?

Thanks,

Paul

> I then tried /dev/usb/acm/0 as a hope of accessing the diagnostic port,

http://bitpim.sourceforge.net/testhelp/hoto-usbintro.htm

The VX6000 has 3 interfaces.  0 and 1 are the modem interface and
are used by the acm driver.  Interface 2 is the diagnositcs
interface and is what BitPim needs to talk to.  It can only 
be accessed via libusb on Linux as there is no driver.

usbscan should list every USB device connected to your machine
(not just phones).  If you aren't getting that then something
is wrong.  Note that if you are working from the source code,
you need to build the USB module in native/usb which also
requires SWIG amongst other things.

The prebuilt rpm has all the right stuff built and links 
dynamically to libusb:

  $ ldd _libusb.so 
  libusb-0.1.so.4 => /usr/lib/libusb-0.1.so.4 (0x400e6000)
  libc.so.6 => /lib/i686/libc.so.6 (0x400ed000)
  /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

None of the LG phones will give up a vendor string except when
they very first get plugged in, and then they tell the OS as
it interrogates them.

> However I know that we should just be looking for the IDs?

Yes, that is what happens.  The strings from the device itself
are shown in the port browser if present.

We also have our own USB ids to string database to augment
the standard one.

libusb accesses the usbfs tree.

It doesn't work like that (except for the modem interface).  The
devices and interfaces appear as nodes in the usb filesystem.

[Paul T. <bit...@st...>]

Thanks!  Now I understand your communications interface.  I didn't wrap
my head around the fact that you couldn't use the native acm module.

Yes, I am building from source because I am running debian linux, and
even after converting your rpm to a deb and installing it, the precompiled
stuff was barfing due to libstdc++ shared library incompatabilities.

I'm sorry I missed that comment about building libusb in the other docs.
I installed swig and built your private _libusb.

So, usbscan is now working properly for me:

Unfortunately, I'm running kernel 2.6.4 (can't go down to 2.4).  I'm
also using python 2.3.

Has anyone else successfully built bitpim out of CVS HEAD under a 2.6
kernel or verified that your libusb works under 2.6?

Re: [Bitpim-devel] linux debugging questions (really USB questions)

[Paul T. <bit...@st...>]

whoops, ignore me.  the timeouts have gone away after a kernel reboot.

I probably screwed the pooch with some earlier debugging.

Thanks for all the help!
