Thinkpads Forum

Hi

i added a 3g modem to my thinkpad x200S recently

it worked for a day, and then stopped working
running debian sid

uname -a
Linux irregularapocalypse 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) x86_64 GNU/Linux

i suspect it's not a hardware problem since i see this in dmesg

dmesg | grep cdc

i tried with 2 different sims .. same result, so i know it's not the simcard


does anyone have an idea on what this might be ?

Hi.
So, may be it affects with system update? But, Debian..
So, I can recommend to you install modem-manager-gui or just mmcli (modem-manager for console) and try to use it to detect your modem.
