UM-175 not being switched.

[Noel J. Bergman]

Binary package hint: usb-modeswitch-data

Ubuntu uses usb-modeswitch[-data] by default now. The default configuration does not enable the UM-175, and probably does not enable other modems.

The default rule:

    # UTStarcom UM175 (distributor "Alltel")
    ATTRS{idVendor}=="106c", ATTRS{idProduct}=="3b03", RUN+="usb_modeswitch '%b/%k'"

does not perform the switch. But this rule:

    SUBSYSTEM=="usb", ATTR{idProduct}="3b03", ATTR{idVendor}=="106c", RUN+="/usr/sbin/usb_modeswitch -c /etc/usb_modeswitch.d/106c:3b03"

works with both Lucid and Maverick.

I suspect that the salient difference in the parameter being passed, but haven't had time to dig into the details.

This may also be the cause of Bug 625110 and similar bugs.

Didier, should the rules perhaps use

  SUBSYSTEM=="usb", ATTR{idProduct}="3b03", ATTR{idVendor}=="106c", RUN+="/usr/sbin/usb_modeswitch -c /etc/usb_modeswitch.d/$attr{idVendor}:$attr{idProduct}"

then? Is that the correct calling for usb_modeswitch?

[Martin Pitt (pitti)]

Indeed there's a /lib/udev/usb_modeswitch as well, but it just seems to be a shell wrapper around /usr/sbin/usb_modeswitch_dispatcher. But since it is set -e, and /lib/udev/hotplug.functions does not exist, this script is broken and won't do anything.

[Martin Pitt (pitti)]

Marking as high, since this will likely affect a lot of of modems, if not all of them.

Oh. Ah. Uh. :-/ I patched usb-modeswitch to use the Debian-specific functions, which are not in Ubuntu's udev. (aka http://patch-tracker.debian.org/patch/misc/view/udev/161-1/extra/hotplug.functions ). Having that patch in udev could be cool indeed.

Anyway, I'm preparing a fixed version right now. Martin: is it possible to get a PPA-style package accepted into Ubuntu or should I first get it in Debian ?
