I have used both the TBS drivers and the open source drivers (ljalves).

In both cases it is possible that there are leftovers from the kernel 
upgrade which prevent the drivers from loading properly.

For the TBS drivers, this is what I do for x86_64 systems:
get latest zip from TBS site, note the use of sudo due to the way TBS 
package the drivers :
unzip tbs-linux-drivers_v160219.zip
sudo tar xvf linux-tbs-drivers.tar.bz2
cd linux-tbs-drivers
sudo make distclean
sudo ./v4l/tbs-x86_64.sh
sudo make
sudo rm -rf /lib/modules/`uname -r`/kernel/drivers/media/*
sudo make install
sudo reboot

The above recipe works for me on Mythbuntu 14.04 (kernel 
3.19.0-51-generic) and Ubuntu 15.10 (kernel 4.2.0-30-generic).

sudo rm -rf /lib/modules/`uname -r`/kernel/drivers/media/*step clears 
out any possible conflicting modules
