Yesterday I got my Banana Pi. I already have RPi in NAS (power goes to active USB hub 2A, where RPi and 2,5" HDD are connected, the other (signal) cable goes from RPi to USB hub), works fine. I grabbed Banana Pi with Raspbian (3.0) and used in the same hardware setup. No boot, all LEDs dark.
Then I disconnected some cables and it booted fine. The problem is: when I connect something on USB, no matter if this is 2,5" HDD or signal cable to the hub, Banana Pi instantly goes down. All LEDs get dark. But it still draws around 4W (at the electrical outlet).
I suspected short circuit on USB, but when cable alone is plugged, it runs fine. It also works with pendrive connected. So it looks a little bit like power issue (but signal cable to USB hub should not take any power). Power supply seems fine and with Banana (and everything) it takes only around 3-5W at outlet. With RPi and heavy load it took over 7W. The problem seems to be with Banana Pi. Broken hardware? Capacitors? Software? Anybody had such a problem? Any ideas how to debug (it's headless and don't have monitor so cannot check screen output)?
BTW It's hard to reach this forum. My normal IP is 85.221.157.x (medium ISP in Poland). When I try to reach forum from that IP, for example release notes, I got blank page. The same problem have friend of mine (but he's using IPpredator VPN, so OK, it might got blocked). Had to use proxy to get to this forum.
