820-2796-a no camera.

[Yoel Ren]

hi, as the title say, theres no camera detected, i have narrowed down the problem to logicboard
my known good logicboard can detect the camera inside customer chassis.

usb_camera_n and p diode mode is same at 0.411
i dont see another line for camera, is the mcp fucked?

Check voltage and diode mode to ground on data lines.
Be sure the camera connector is good.

All the other USB devices are in working condition?

smbus_smc_a_s3_scl : 0.470
smbus_smc_a_s3_sda :0.479
smbus__mcp_0_data : 0.424
smbus_mcp_0_clk ; 0.424
all of the voltage above is 3.3v
other function is okay.
camera connector is sure good.

Aaaa, you've already posted 0.411 for both lines.
If voltage is also the same, then MCP problem...
