I am trying to connect my Avalon Controller to my Raspberry Pi (raplacing the TP-Link module with an Raspberry Pi)

When I use:

cgminer -o uk1.ghash.io:3333 -O x.x:x -D --verbose --avalon-options 115200:16:10:45:1024:55 --api-allow "W:127.0.0.1" --api-listen

I get an error like:

AVA0: Get avalon read got err 0

Someone can help me with this?

Here is the cgminer log:
