Hi,
I develop an application with Openframeworks and two usb peripherals. The two peripherals are : a webcam and an usb board. The problem is the next : when i send signals to the board, the webcam freeze. Can Openframeworks manage severals peripherals in same time? Sorry for my english and thankx you for the answer!
what usb board are you using?
have you tried plugging the camera and the usb board into different usb ports on your computer? perhaps the camera is saturating the usb bus (filling it up with data)?
