Hi, uname -a Linux Firen4ALL 3.17.3-031703-generic #201411141335 SMP Fri Nov 14 18:36:40 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux Gives me the following in the syslog when I attach a Huawei E173 3G USB modem to my computer. I don't know if it's relevant but the modem supports storage though there is no SD card inserted in it.
