 Hello. I want to show the effects of a bad USB cable. So I have a power bank here and here an HCR-F1 with a porta pack. And this cable is actually a bad cable. When I connect this the porta pack starts up and then if I go to capture for example the screen goes black. That is actually because the porta pack here is drawing more power than can go through this bad USB cable and so it shuts down. I have one other cable here, another USB cable. This one is a good one. And as you can see here when I go to capture then the capture works. So the porta pack with the HCR-F continues to work. The problem here is the USB cable.
