- Problem USB Port
Rasberian to use with a Raspberry PI I noticed some disconnection problems with USB port while using Raspbian Jessie (2016-05-27-raspbian-jessie-lite.img). I rollbacked to Raspbian Wheezy (2015-02-16-raspbian-wheezy.img) and the problems solved by themself magically... For now, I have not investigated this issue, but if you experience some "Caught signal 11" error message, it could be this same problem. For now, I would recommend Raspbian Wheezy v2015-02-16.
