pl2303: only root can use port
Last modified: 2013-03-13 11:50:40 EDT
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):
Steps to Reproduce:
Tested more. It seems the problem is deeper, because ftdi_sio devices are also affected.
Are you still seeing this with 3.7.9 or 3.8.2 in updates-testing?
No, after upgrading to F18 3.8.2 problem is gone.
