There is no sg++ in whole drivers/media/pci/cx23885/ directory.

kernel: Gentoo Hardened kernel 3.18.1 (hardened part turned off)
media_build: pure original media_build
media tree: https://github.com/ljalves/linux_media (original linux-media 
plus some
new out of kernel TBS drivers (from this tree I need TBS6285 driver))

For tests I use only command line tools: w_scan & dvb-fe-tool

Tests:
1) w_scan on first front end then after 5-10 seconds w_scan on other
2) w_scan on second front end then after 5-10 seconds w_scan on first
3) "dvb-fe-tool -d DVBS" on first front end then after 5-10 seconds 
w_scan on second front end then after 5-10 seconds w_scan on first
4) "dvb-fe-tool -d DVBS" on second front end then after 5-10 seconds 
w_scan on first front end then after 5-10 seconds w_scan on second

w_scan run on both front ends simultaneously.
