we currently only have
/lib/udev/rules.d/77-probe-modem-capabilities.rules in udev-extras; I
assume make install installs that file now? If so I will add it in
next package upload.

Its a bit strange; with the latest udev-extras from above, running:

udevadm info --query=env --path=/sys/class/tty/ttyUSB0

I get:

ID_MODEM_PROBED=1

while the modem-prober (from udev-extras for now) gets:

/lib/udev/modem-probe --export /dev/ttyUSB0 
ID_MODEM_GSM=1
ID_MODEM_PROBED=1

The versions we have in jaunty are:
 libudev-dev           138-1
 udev-extras           0~-2~gite5fb9bd-1 (which is a 4 days old snapshot afaik)


I assume the disappearance of  ID_MODEM_GSM is the reason why we fall
back to hal detection here. Any idea?

(Will try the .rules from NM next).
