this one last problem.<br>
<br>
I change channels with serial connections to my 2 DirecTV boxes. 1 on<br>
the serial port (works great) and 1 on the USB port (works great from<br>
the command line, permission issues when issued from the backend).<br>
<br>
Here's the command I use on the one that doesn't work:<br>
/usr/local/bin/d11channel.pl box_type D11 port ttyUSB0<br>
<br>
Here are my permissions:<br>
bderman@mythtv:/dev$ ls -l | grep USB<br>
crw-rw---- 1 root dialout 188, 0 2008-08-11 10:19 ttyUSB0<br>
<br>
Here's what I get in the backend log:<br>
Could not open ttyUSB0: Permission denied<br>
<br>
mythbackend is running as the mythtv user<br>
I can log in as my user (bderman) and issue:<br>
/usr/local/bin/d11channel.pl box_type D11 port ttyUSB0 11<br>
<br>
and it will change to channel 11.<br>
<br>
Also, if I chown mythtv.mythtv /dev/ttyUSB0 I get the same error from<br>
the backend, but working correctly from my user from the command line.<br>
Same thing if I chmod 777 /dev/ttyUSB0. In all cases it works ok from<br>
the command line and I get a permission error in the backend.<br>
<br>
Also note this was all working ok in Fedora 8. Any help is appreciated.<br>
