Windows 10 Creators Update bug: USB 3.1 Port shown as Unspecified

I'm even more curious about this:
"i have to update the bios to the latest version, F21 something that I do not suggest because it gave me a lot of system instability".

Was the F21 BIOS a Beta version?
What was the system instability?

It is unusual for a non-beta BIOS to cause instability and could possibly indicate a malfunction of some sort on the motherboard.
It is also important when updating a BIOS to first reset the existing BIOS to default settings before starting the flash. Customized BIOS settings can mess with a BIOS upgrade installation.

Well actually i just made a fresh install because i ended with a big mess. No, it did not solve the problem, even after a new install i have this USB 3.1 Port Unspecified. This only happens with the creator update, not with any other previous windows version. I have posted on gigabyte forum, there are other post with similar issues, it seems some kind of drivers problems and the last version of windows 10.

You are probably right. I did not realize you had done a fresh installation. That is the nuclear option and eliminates a lot of possible problem/solutions.
Most likely growing pains with Manufacturer drivers not keeping up with Windows builds, or Windows builds not being backward compatible with old drivers.

Hi,
Yes i setted everything to default in the BIOS before i updated it. No, version F21 is not beta and it is required to install USB 3.1 drivers, but i dont know if i should use this version because they state after F20 version that you need this version for Support 7 generation CPU and F21, V core Voltage adjust, so i dont know if i can use those version of the BIOS or keep the F5 the last one they released for the 6 generation CPU.
I was not able to access to the BIOS after restart with the BIOS F21, when i restarted the computer just a black screen showed up, it did not happen if i turn on the computer.
I also had some BSOD with this text, {your pc ran into a problem and needs to restart}, The only way i was able to go into windows again was as safe mode with network connections it never happened with F5 Bios, and now that i downgrade to F5 Bios version everything is working properly except for the USB 3.1 Port Unspecified.
Btw the physical USB port 3.1 is working properly at least if i insert a 3.0 or 2.0 usb stick there.

Have you considered trying the F20 BIOS?

The statement: "version F21 it is required to install USB 3.1 drivers" sounds like the solution here. The question then becomes why the F21 BIOS version wont work.

BIOS upgrades add new features and functionality. They don't list all of the changes made in each version on the download page, just the "most relevant" ones. So it doesn't matter, in most cases, that you don't need the featured upgrades, there are often others and bug fixes that you can use. In general it is always best practice to run the most recent BIOS made for your motherboard, but there are exceptions.

It sounds like you ran a BIOS update from within Windows. While this method has greatly improved over the years it can still be problematic in some cases.
Do you know if there is an option to flash the BIOS from within the BIOS?

Your USB 3.1 ports are probably running in USB 2.0 mode. Maybe 3.0

It is always helpful if we know what hardware you are working with. If you fill out your system specs then we could see that info.

Here is the BIOS method: Q-Flash

Had something of a similar issue as posted in the Gigabyte forums at overclock.net. However mine didn't arise until after I updated my BIOS to F21, before the Creator update!

That said, if the board supports Thunderbolt, make sure you install both driver and firmware update. And as many have said both chipset drivers and SATA drivers. Once this is done, reboot, than after that, if the issue is still there... completely power off the machine, to include removing the power cord! Wait about 30 seconds, power back on and see what happens.

Let us know.

And yeah, for some odd reason the F21 BIOS causes some weird issues with the some USB ports. Gigabyte is clueless here, and claim they know nothing about the issue. I know because I called them on this. They promised to get back to me on it but they never did. That was 3 weeks ago. Anyway have a look at my post for clarity. And let me know if this helps.

Peace

The F21 BIOS is not beta.

And yeah, it is unusual for a "stable" BIOS to cause issues, but somehow Gigabyte managed to accomplish this, at least on some machines. The big issue is that F20 and up BIOS's completely changes the look and features of the old BIOS since it's main purpose is to add Kaby lake support to their (gigabyte) Z170 boards. That said, you are warned that updating to these BIOS won't let you "downgrade" to your previous one.

Prior to the F20's, most all of Gigabyte's Z170 boards had sub 8 BIOS's. That is most of the BIOS's were in the F7ish range. Prior to updating my Z170X Gaming GT board I had an F7c Bios. After these, Gigabyte jumped to the 20's where they added support for Kaby Lake processors to most their Z170 boards.

The first Kaby BIOS's had over-volting issues with Sky Lake processors. The fix was the F21/F22 BIOS (some boards have an F22 BIOS) which "adjusts" the V-Core voltages. Current BIOS for the OP's and my board is F21.

Anyway, I too had weird issues when I upgraded to the F21 BIOS such at that of the OP's issue as well as a TPM module issue. The TPM issue seems have sorted itself out so.

That said, I've been updating BIOS's since I got into PC's, always opting for the latest one, and this is the first BIOS I've ever had issues with in my 20 years of PC building.

At any rate all this is just FYI.

Peace
