[Bug 889411] Re: [Samsung CMC-370] MEZON modem not detected

 

It's an established Ubuntu policy that another person (not the original
reporter) should confirm the bug separately:
<https://wiki.ubuntu.com/Bugs/HowToTriage#Confirming>. I have searched
for existing bug reports and upstream reports (that would have allowed
me to confirm your report straight away), but with no success. (Sorry if
I may seem rude or absurd).

As for your second observation, I'm trying to reproduce the bug myself
and (in case) open a second separate bug report. Thanks for pointing it
out.

Title:
  [Samsung CMC-370] MEZON modem not detected

Status in “madwimax” package in Ubuntu:
  New
Status in “network-manager” package in Ubuntu:
  New

Bug description:
  The SAMSUNG SWC-U200 MEZON USB modem (store link, in Lithuanian:
  <http://www.mezon.lt/isigyk/papildoma-informacija/atnaujinkite-mezon-
  usb-modemo-tvarkykles/id/712/>) is not detected by the most recent
  version of NetworkManager (trunk version available at ppa:network-
  manager/trunk on November 12th, 2011) even if the most recent drivers
  (madwimax_160-0ubuntu1_amd64.deb) are installed. This makes some
  applications that detect if an Internet connection if present (e.g.
  Software Center) break.

  Workaround: stop NetworkManager (sudo stop networkmanager), so that
  applications that query NetworkManager will operate in "fallback" mode
  (they assume a connection has already been established).

  Log files are in comments #6 and #8. Relevant lines taken from a NetworkManager debug log:
  NetworkManager[2254]: <warn> /sys/devices/virtual/net/wimax0: couldn't determine device driver; ignoring...
  /sbin/ifup: interface lo already configured
