So we know now that:
- the problem does not come from your lightshow
- the problem does not come from the dmx interface
Could you please now try the same configuration (empty lightshow and no dmx interface), with the program "
TheLightingController_NoHardware_Debug.exe" ?
(available here:
http://download.thelightingcontroller.c ... _Debug.zip)
FYI, this program does not communicate at all with the external librairie which control the dmx interface. Afterwards, we will know if the problem comes from the external librairy or not.
BTW, please confirm also that there is no sleep or energy save active process in your system, which could force the usb to stop for instance.
