They work ok on linux after figuring out the usb_modeswitch stuff, but now I'm stuck with getting them to do USSD. I am getting the exact same symptoms as in this thread: <a class="moz-txt-link-freetext" href="https://lists.freedesktop.org/archives/modemmanager-devel/2014-August/001487.html">https://lists.freedesktop.org/archives/modemmanager-devel/2014-August/001487.html</a> I see no signs of work being done on adding this support either in this mailing list, in the bugtracker or the git repo, so I'm pondering writing a patch to get my modems to work (I want to query the prepaid credit status of the modem). So my questions: - has USSD via MBIM been implemented and I missed it? - if not, how hard would it be to write the missing code if I've never looked into MBIM or modemmanager code? - any pointers to relevant documentation for MBIM? Thanks! Laurent </body> </html>
