Hi tnx for answer. I am not using any usb hub. It has happened very rare but it has happened a few time or so.
True i can fire up a gui and get it out of bootloader.
But if i am not mistaken the command:
"flirc_util dfu leave" should do the same, but is says command successful and that the flirc is out of dfu but in reality it does nothing. The gui works to kick out of DFU and flirc_util does not. So there is probably no reason that GUI should be able to kick flirc out of DFU and flirc_util would not.
And also flirc_util upgrade firmware is useless ATM since there is no more seperate .bin files available. I hope you are planning to release them. I am a command line user when in linux and i do not use GUI at all nor have any GUI installed in linux. And when managing remote systems, cmd line is the most powerfull tool i can get without user interaction.
I am not trying to troubleshoot mine Flirc :) I am reporting bug that DFU kicking out in flirc_util does not work :)
