Title:
Switching of Samsung LTE modem does no longer work in Natty+

Josua, can you get this updated file attached into the next release. It
has the line Configuration=-1 added. We should have an updated version
of the data package for Oneiric.
Ubuntu packager: if we don't get a new version, the current version
should be patched with this change.
** Attachment
Hmm, Configuration=-1 is usable only from usb_modeswitch version
1.1.8. Starting with that version, the configuration check is skipped
anyway if bNumConfigurations is 1; this applies also to the Samsung
device.
In short, updating just the config file with 1.1.7 will fail - updating
the program
Note: the current version is 1.1.9 which adds support for the Cisco AM10
Wifi stick. Just mentioning.

Re-reading the bug thread, I noticed the problem in #25.
The usb_modeswitch automatic framework will skip the configuration
test; actually it will run the binary with the -u -1 parameter.
Your test in #25 failed because you called the binary manually on the
commandline. If you want, test again
Josua, thanks for investigating this. You are right, it actually works
fine when I tested the latest Oneiric alpha.

If you want, test the freshly released version 1.1.8 from source. Debian
packages should be up soon but are probably not fully compatible with
Ubuntu.
I changed the logic and the implementation of the active-configuration
check. This check will now only be done if bNumConfigurations is
bigger
Okay, I tried it now. Just running it gives:
$ sudo ./usb_modeswitch -IW -c /etc/usb_modeswitch.d/04e8\:689a

Hmm, could we get a backport of just that new feature into 1.1.7
version, so that we can get rid of this bug before next Ubuntu?

Strange, on another ARM based NAS box, I get a timeout even with v1.1.4:

Configuration is global, like the other switching parameters.
If the current configuration cannot be determined correctly, configuration
switching will be skipped. This will not affect YOUR case.
So you are saying you get the next error during interface class
detection? I'm beginning to suspect

Japp, it looks exactly like in that forum post. What about using options
to usb_modeswitch to make it behave like before for this modem and set
those in the config file for the device? Are all the options
configurable through the config file now?
I know the device is very quirky. Seems like they
Hmm, where is this change? In get_current_configuration() there is no
Configuration variable. Then the if (Configuration) doesn't make
sense. Do you have a patch against the Ubuntu patched version?
I tried something similar, and then I got: Error: getting the interface
class failed. Aborting.

Before version 1.1.5 some devices popped up which want to be switched by
changing the device configuration. USB allows to provide multiple
internal modes that can be set with SELECT_CONFIGURATION.
In fact, that is how the whole mode switching SHOULD have been
implemented while following the
Copy-n-paste error in line 4 of the code. It should look like this, of
course:
fprintf(stderr, No configuation setting possible for this
device.\n);

Again, the offending line is the one I posted in #4. The time-out for
this control transfer is set to 1000 which is one second.
Can you try to change that to 2000 or more and see if there is any
change?
