I'm assuming you are referring to the rtsx_usb_ms driver ?

What is the oddest thing right now, is that none of the rtsx modules are
reported loaded.

rrs@learner:~$ lsmod | grep -i rts
2016-09-21 / 17:07:08 ♒♒♒  ☹  => 1  

where as the module was built for the kernel, and does load when asked manually.

rrs@learner:~$ less /boot/config-4.8.0-rc7alxb+ 
2016-09-21 / 17:07:54 ♒♒♒  ☺
