Topic: Connecting USB device to 2 non-battery ports = silent freeze
Just what it says.
What's the deal?
If i plugin anything (even a USB flash stick etc) into one of the non-battery powered ports (the two that are on side of board opposite from power connector, it just silently locks up.
If i connect something and power things up, it works - no freeze, device is recognized.
I thought the issue could have been power but I've reconnected to a clean lab supply and total current draw with my USB dongle in powered port and USB flash drive in unpowered port is ~500mA.
