Hello, (FYI - This is also posted on another forum) I think I messed up the grounding of my front panel ports (all of them). My case is a Coolermaster Cosmos II and I decided to swap the USB 2.0 ports of its front panel with USB 3.0 (extra) ports and a USB type C port since my motherboard supports it (got a Lian Li Type C cable). So I took out my knives, razors and Dremel and removed the USB 2.0 ports but I also cut the grounding cable that loops from one USB port to the other. Now I don't want to have those ports ungrounded so I was wondering if it is ok to solder a wire on each of the USB metal shield (outer shell) and send all of them to the grounding wire that goes to the case. From what I have gathered grounding straight on the USB port metal casing is not a bad practice. What do you think is it safe to do so? Here is a pic of my ports - the gaps will be filled with USB 3.0 ports. The yellow circles show the old wire path and the red circle is where I suggest to attach a ground wire for each port and then to the case.
