Here's what I see with the new kernel:

[john at HP_Box ~]$ dmesg | grep adapter
[    1.845944] DVB: registering new adapter (Kworld UB499-2T T09(IT9137))
[john at HP_Box ~]$ dmesg | grep DVB

[john at HP_Box ~]$ uname -r
3.10.0-123.13.1.el7.x86_64
[john at HP_Box ~]$

I guess I should report to the linux-media list.

... and earlier I haven't been able to find an effective form of 
/etc/modpobe.d or /etc/modules-load.d to fix the adapter numbers.
