I have just verified that upstream uses the same udev rule file:

https://salsa.debian.org/debian/usb-modeswitch-data/raw/debian/master/40-u=
sb_modeswitch.rules

Therefore upstream obviously expectes /lib/udev to be part of the $PATH,
meaning that it cannot be usb-modeswitch-data's fault if this is not the
case.

Created a new bug entry for the eudev package.

Please close this bug!

First of all, I am using the "ascii" branch, not "stretch".

I also think now the problem is not the rule-file but rather the fact
that the PATH is set up wrong for the eudev service.

The following modification made the problem go away:

$ diff -u /etc/udev/udev.conf.upstream /etc/udev/udev.conf
=2D-- /etc/udev/udev.conf.upstream        2019-06-13 23:14:29.000000000 +0=

+++ /etc/udev/udev.conf 2019-06-13 23:15:17.000000000 +0200
@@ -4,3 +4,5 @@
  # initramfs should be rebuilt.

  #udev_log=3D"info"
+
+PATH=3D/lib/udev:$PATH

because it puts /lib/udev at the front of the PATH, making the udev rule
invoke the correct executable.

Package: usb-modeswitch-data
Version: 20170120-1

The /dev/gsmmodem symlink is very useful as the device specified in
/etc/ppp/peers/* configurations, because it works no matter what modem
has actually been connected to the computer.

The eudev-rule from the the beforementioned package invokes the
usb_modeswitch binary with the --symlink-name which used to create the
/dev/gsmmodem symlink:

$ grep -A2 gsmmodem /lib/udev/rules.d/40-usb_modeswitch.rules
# Adds a symlink "gsmmodem[n]" to the lowest ttyUSB port with interrupt
# transfer; checked against a list of known modems, or else no action
KERNEL=3D=3D"ttyUSB*", ATTRS{bNumConfigurations}=3D=3D"*",
PROGRAM=3D"usb_modeswitch --symlink-name %p %s{idVendor} %s{idProduct}
%E{PRODUCT}", SYMLINK+=3D"%c"

The binary ignores the option, and hence no symlink is created.

I think the udev rule is incorrect and should invoke the
/lib/udev/usb_modeswitch shell script rather than the
/usr/sbin/usb_modeswitch binary, because only the shell script supports
the --symlink-name option.

This is at least the case in the current version 2.5.0+repack0-1 of the
usb-modeswitch package.

I am using Devuan GNU/Linux 2.0 (ascii)
on branch stretch
with kernel
Linux xeeepc 4.9.0-9-686 #1 SMP Debian 4.9.168-1+deb9u2 (2019-05-13)
