Currently I have the front panel USB plugged into F_USB1. Should I plug this into F_USB2?

Yeah. Just to keep things simple. Plug the Bluetooth cable to F_USB1 and your front USB to F_USB2.

I'm surprised there are still so many cases that only have USB 2 ports in the front...

Thanks!

One thing that strikes me is that cases seem to stay in production for some time. Counting the 2 side panels as 1, there are 7 unique panels in my case and, unless they are shared with another product, you need 7 sets of stamping dies to make a complete case. Coupled with the standardization for ITX, ATX, etc. it doesn’t surprise me that a given model stays around for a while. I bought my Silverstone PS07 in 2014, but I’ve seen a test and review from 2012 and it is still being sold. Certainly by now the $$ for tooling costs have been recouped many times over which would suggest that a model that has been around for this long is pretty cheap to make...

Last year, I picked up a cheap case and it came with USB 2 ports too. But I hated it and ended up buying one of the following for a few bucks to convert it to USB 3. It was almost a perfect match for my case. Even the mounting holes were near perfect. I can't imagine using this instead of the USB 2 version that came with the case could have add much if any cost to the production...

Ooopppss...

I have to take back what I said. As I’ve been working on the motherboard, I haven’t been looking at the front of the case. The 2 front USBs on the case are blue 3.0, but the cable that was in the F_USB1 was from the card reader which has 2.0 and 3.0 ports. The 3.0 from the card reader exits as a standard blue connector to be inserted into a 3.0 connector on the back plane. The front USBs go into a double cable that goes into the F_USB30 connector...

You are going to hit the USB 15 port limit. You're going to have to pick and choose which ports you want to disable.

Ah, I remember that you have mentioned that before. If you have a USB hub with 3 ports, does that count as 1 port (computer to the hub) or as 3?

Anyway, it looks like this:

Case Front: 2x USB 3.0
Card Reader: 1x USB 3.0, 3x USB 2.0
Back Plane: 4x USB 3.0, 1x USB 3.1, 1x USB 3.1-C
Fenvi: 1x ??

I could easily forgo the 3x USB 2.0 ports in the card reader if needed. Am I missing something? On second thought, that would probably kill the card readers, wouldn’t it?

USB 2 ports count as 1.
USB 3 ports count as 2 (one USB 2, one USB 3).
USB 3.1 gen 2 counts as 2 (one USB 2, one USB 3.1).
The Bluetooth part of Wi-Fi/Bluetooth cards are just USB 2 devices so they count as 1.

All the ports you listed count as 26. You will have to choose 11 to disable.

Please see the following for more info.

Hi pastrychef,

I am encountering some issue with my WiFi (I have exactly the same card as you). It seems that there's a conflict with the country code in MacOS (US) and my router (which should be : CH or DE) [btw I live in the Italian speaking part of Switzerland].
When I was using Clover, I had read somewhere that you could set this parameter "brcmfx-country=#a".
I've tried it with brcmfx-country=DE but there's no change.
By chance Do You know if there's something similar in OpenCore ?
Thanks a lot

You can try the exact same boot argument in OpenCore. Add it to config.plist > NVRAM > 7C436110-AB2A-4BBB-A880-FE41995C9F82 > boot-args. You can add it to the end of the line after a space.

Thanks a lot pastrychef, it worked. Unfortunately I am having some troubles with the signal's strength.
