ROS PS3 Distorted camera feed

Hello

I have two PS3 cameras that work well. Only when connected directly to the intel NUC. When connected to a extension usb adapter the video signal becomes distorted. I believe its something to do with the power supplied to the usb extension adapter its not enough for the cameras.

Hope you can help.

Obvious question: have you tried a powered hub?

The PS3 cams are special in that they use USB bulk mode for data transfer (you can get more info by googling "PS3 camera bulk mode"). This has the advantage that it allows to transfer more data (and the reason why the PS3 cam is one of the few cams that can do 60FPS over USB 2.0), but it in my experience can be problematic in less than ideal conditions.

I know I saw issues when oversaturating the USB on a machine with too many PS3 cams streaming high rate images. In that case, images also got randomly distorted.

Have you tried different kinds of USB extensions? Also, have you tried other types of webcams?
