[bluetooth-dev] "Operation not permitted" in user mode



Dear all,
 
               I am using redhat 6.2 and Ericsson Bluetooth Application and Training kit for testing the openbt 0.0.8. When i enter the user mode, it shows" Operation not permitted" after initizing the stack. What is the problem???
 
               Thank you for answering my question.
 
Regards,
tim
