Description of problem:
Despite all access rights were set properly for user for /dev/ttyUSB* nodes, user can not open them. It seems only root can. I checked access rights:
crw-rw---- 1 root dialout 188
The user is in dialout group and can perfectrly open ports with the same access rights but belonging to different modules. I also checked if port is used by someone else by fuser, it's not. Still I get "Device or resource busy" error every time I try to open port for r/w.
Also if I disconnect my convertor and reconnect it again, node name is changed (number is increased by 1).


Version-Release number of selected component (if applicable):
kernel-3.5.3-1.fc17.x86_64
