Why doesn't the webcam work on Debian?

Question

Debian

There was a web-ka, it worked great. I decided to extend the wire with a twisted pair cable. I soldered it, I checked the contacts with a tester. All OK. I connect - does not see. Piggy and the seven see perfectly, install drivers and show the picture normally. Wire length 5m. Tell me what is the reason and how to implement a long wire? Yes, more. I connect through an active hub.
