The question is not one of reminding me of what I said earlier....
it's one of pointing people in the right direction. Frankly, some of
the fault for this patch lies with Greg and myself for letting it
through. I had just assumed that the Huawei guys had already been in
touch with usb-modeswitch for some reason, and that this was just an
optimization of existing logic (not an expansion).
I was contacted at one point by a Huawei engineer who convinced me to change the default mode-switching 'message' for all Huawei devices.
The reason was the introduction of an 'advanced' Linux driver by Huawei which requires a specific target mode. This was in October 2010.
No contact attempt since then.
Who is maintaining usb-modeswitch these days, anyway? The comment in
the file should point people directly there....
I never ceased work on it and intend to do so for years to come. I would certainly welcome any pointer to the usb_modeswitch main site in the code or the documentation. Although modem developers or engineers should not have a problem finding the site and providing new device information.
And, as of now, I would really like to see as many of these devices
migrated (albeit slowly) to using usb-modeswitch wherever possible. I
know there are a few devices for which that might not be possible, but
I am DONE dealing with this same issue over and over and over again.
It will certainly be work to migrate support; maybe we should wrap all
the relevant unusual_devs.h entires with
CONFIG_UPDATED_MODESWITCH_INSTALLED_SO_MAKE_THESE_GO_AWAY during a
transition period?
I think it's safe to say that usb_modeswitch is included in all distributions now. Usually, no user interaction is necessary.
I guess the real problem will be verifying that all of the entries *can*
go away. This type of hardware tends to get old very fast, but there is
always someone having a really ancient device.
I will check this and add any missing USB IDs to usb_modeswitch, but I can't shake the feeling that not *all* Huawei entries in "unusual_devs.h" did actually materialize as devices ...
Anyway, as Bjørn said, putting that initialization into the storage driver takes away quite some possibilities to handle these modems in a flexible way.
