Hi to all, I have Philips android tv 43pus7000 series with two USB ports. First usb is 900 ma, the second 500 ma. Both are 5V, but whatever I plug into second port it is not recognised. The only I can do is charging my phone. Do anyone have experience with those TVs, is this normal? I hoped to plug keyboard and flash drive, but looks like it can not be done. Regards!
