Prompt [Q] Enable Logcat on unofficial-JB-4-1-2-stock rom

Hello,

I flashed following rom to my Xperia U

http://forum.xda-developers.com/xper...1-100-t2420029

now I wanted to test my App on this rom, but logcat only displays the message: "Unable to open log device '/dev/log/main': No such file or directory"

how do I enable logging on this rom?
