I have a usb camera module which works fine when I plug it directly into the PC. But when I try to use a hub or even an extension cable, it either says "USB Device Not Recognized" or nothing at all. Both the hub and the cable work fine with other devices.

Any ideas what could be causing this?

By the way, the camera module had 5 leads, V+, D+, D-, Ground and another one that has to connect to shield. Not sure where do I connect it to?
