Hi DynaxSC,

I really appreciate your comment, I tried to measure them with resistance mode but at first I was very confused because I didn't know where to put the probs so I tried on every ESD chip and it was hell of a challenge because I don't have a microscope,

so I measured them and no short appeared (one prob on GND and the other on each pin), I double checked and it's the same, so I tried with Diode mode, I couldn't see anything significant except for 2 pins on DU5 (the left 2 bottom pins) their measurements were off compared to all other pins on every similar ESD...

Thank You mate


I'm sorry I didn't come back earlier but I was out of town so couldn't give you the measurements

I did what you asked me to do and apparently there is two open lines (OL) on the faulty USB C/3.1

I tried to write all the measurements on the boardview and it get messy with all the numbers, I tried my best to make it clearer and less messy so I apologize if it isn't clear

please let me know if I can make anything to fix that.

*ps: I posted this post on 3 other forums, you are the only decent guy/gal who didn't...

Hi there,

Recently I had a problem with my msi z170a m7 mobo usb c/3.1 port,

The port connects normally but when I transfer data it transfers with full speed (from the pc to the device I'm sending to) but it does not receive with the same speed, to make it simpler, if I plugged a wifi adapter to it, I can upload with full speed but I can't download with the same speed, but if I connected the adapter to different port it downloads at full speed.

I'm not sure if it's a HW problem or a SW one,

I have MSI z170a m7, with modded bios to install coffee...

hi there,
my name is Belmoto
to be honest I just joined this forum to find help with a problem I'm currently having with my Mobo, I'm really sorry for the small intro but I hope I will be an active member on this forum from now on
