Hello,
I have a customer switch v1 to repair with prior attempt on the USB C Port with a lot of missing pad,
i replace the M92T36 and restored the pad needed to get charging on both side and the USB Data line to get RCM injection working
It work i got fast charging on both side, but no detect when plugged in RCM mode and i found out the USB Data line D+ was reading OL on the motherboard so not a soldering problem (same issue on D- here)
I inspected the board to see if i can found where the problem coming from when i found 2 missing component :
I don't have any value for this component from what i can see it's a diode and a capacitor ?
Can it be related with the problem above because apart the usb problem the switch work fine but the customer really want to get rcm working on his switch
Thanks
