Hi greg k-h, The module si2168 has been changed in Linux 4.9.*, so I only done a diff on the module. Don't know if the issue is on this one, could be something else. I will try to check this out with git bisect, but I'm not an expert and don't know stuff about hardware stuff.
This is the output of a working T230 on Linux 4.8.14: [ 7999.575183] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
