Re: CH340

I think that all mentioned converters are fake ( the price is too low ) - but each one is working on Windows environment. So I think that driver in raspbian can not operate each chipset ( fake ) clone. Any bytes are transmitting but I receive something else that I send. So I buy one piece for test a...

There's a bug in the piface library code that's exposed by the 3.18 kernel. Why are you using a forked version? Try reverting to the stock code (which gets installed with apt-get). https://github.com/piface/libmcp23s17/issues/8 I try to zero structure before a use it, but the result is the same. An...
