Ok, with a usb hub with external power, still do the same thing...

I am able to configure external bluetooth module if only bluetooth module and mouse/keyboard are connected. For some reason mouse/keyboard do freeze if i connect mouse/keyboard + bluetooth + arduino(canbus messages to keypress) + hifymediy sound card.
After the configuration, if i connect only bluetooth module and sound card + all work but if i connect arduino on top of it - bluetooth does not connect.
Also i did a test and if i connect arduino after the boot and after the phone is connected - all is working fine.
