Question [Q] Smartdock mode Tab 3 8.0

Has anyone actually got a Tab 3 8.0 into smartdock mode. I have installed as the kernel 3.0.31 GalaTab3_8.0_v14.4.3 and whilst an home made OTG cable works fine replacing the shorting link with a 64.9 ohm resistor and linking it both to a USB device and the PSU results in no charge being received by the tablet.
