820-3332, No Camera

It is a simple USB device. Measure both USB data lines at the connector on diode mode. I assume you tried a known good camera

Hey Duke, thanks. Yes, it was tried with a known-good assembly/camera (two, actually). Same issue on both, "no camera detected", etc. In diode mode, I get:

pin 1: .000/gnd
pin 2: .470
pin 3: .470
pin 4: .400 (.470 on a good board)
pin 5: .589
pin 6: .589

Diode mode readings match a known-good board on all pins except pin 4, which is lower than it should be I believe.

Any other USB devices not working like BT or ports? If all other USB is ok, check if diode mode on pins 2 and 3 change when plugging in the camera. Could be bad connector or L3508.
