USB 3.1 Gen 2 issue with Gigabyte GA-AB350 Gaming 3

Support
1

I am having problems trying to get USB 3.1 Gen 10 Gbit connection with my MOBO.

I bought a 10 Gbit cable on Amazon to get this speed with my Logiitech Brio 4k Web Cam

I have Gigabyte GA-AB350 gaming 3 MOBO

When I plug the Web Cam to the USB 3.1 port I get 480M USB link and in the USB 3.0 port I get 5000M USB link. Below terminal output. I have to research if the Web Cam doesn’t support this USB Link speed but maybe someone has the same issue and we sort it out.

Brio Web Cam on 3.0 port and mouse/keyboard on USB 3.1 port

UPDATE:

I used the original cable which is USB 3.0 and from Logitech and I still get 480Mbits on both of the Red USB 3.1 Gen 2 Ports.

99% sure that webcam only supports 5Gbps, which is why it’s maximum frame rate is 4K @ 30fps.

The 3.1 port should fallback to that speed so there’s something wrong there. Probably the port itself since the cable + cam work correctly in the 3.0 port. Test it with a different device.

inxi might tell us if you have a BIOS update

yes that’s the first thing you should do. a web-cam with 10Gb/s is very vague.

you wrote:

relating to the manufacturers site:

it’s usb 2.0 !

5

So…

USB 3.0 = USB 3.1 Gen 1 = USB 3.2 Gen 1×1 → 5 Gbit/s
USB 3.1 = USB 3.1 Gen 2 = USB 3.2 Gen 2×1 → 10 Gbit/s

One of the 4 blue ports on the back?

One of the 2 red ports on the back?

When I read the specifications of the webcam, then It supports only USB 2.0 and USB 3.0, so only 480 Mbit/s or 5 Gbit/s , there is nothing between or more.

Ordinarily you would assume that it runs on USB3.1 at the speed of USB3.0, but here for unknown reasons it runs on USB2.0 speed.

Gosh… i read the manual and found that:

grafik
grafik1030×108 15.5 KB

grafik
grafik1024×101 20.3 KB

In simple words:

  1. Webcam only supports USB2 and USB3. Period.
  2. Back panel:
    • Blue ports only support USB 3.1 Gen 1 (USB3) and USB 2.0. Nothing else.
    • Red ports only support USB 3.1 Gen 2 (USB3.1) and USB 2.0. Nothing else.

Plugin the webcam in a red port and it will only use USB2, since the webcam only support USB3 (blue ports) and USB2 (black port).

End of story: It is a hardware limitation and not a Manjaro issue.

Correction: The hardware should support 5GBit/s on USB3.1, since it is backwards compatible to USB3.0, but for an unknown reason it doesn’t, but backwards to USB2.0.

:notebook: Read the second screenshot again and don’t believe everything what I write. :innocent:

So the USB 3.1 ports only support 10 Gbit or 480MBit so the camera falls back because it doesn’t support more than 5 Gbit and that is not supported by the MOBO on that port?. I missed that, never imagine the ports could not do 5 Gbit.

7

Yes I read the manual but I guess I was biased because I expected the port as being 10 Gbit capable would have the physical capability of linking in 5 Gbit. The camera does link to 5 Gbit on USB 3.0 ports. This is my first PC and I am learning

8

Huh? It quite clearly says they they support 3.1 Gen 2 (10 Gbps), 3.1 Gen 1 (5 Gbps), and USB 2.0.

Backward compatibility is required by the USB specification. A 10 Gbps port must also support 5 Gbps. So a 5 Gbps device should connect at 5 Gbps in either of those ports.

That’s the good part of the USB-IF’s work. The bad part is the absolutely crazy 3.x naming shenanigans.

9

Yeah, that is what I thought, maybe Gigabyte made it non-compliant?

10

No, that would be a good way to get sued.

Have you got any other USB 3 device you can try in that red port to see what speed it connects? Flash drive? Phone? And I assume you tried both the red ports?

Yes I have tried both. This is what Gigabyte told me, ti seems it is a driver or hardware issue itself:

Good day. When the port detects that the device is USB 2.0, it will only work as USB 2.0 at 480Mbit/s.
If the device is USB 3.0, 3.1 Gen 1, or 3.2 Gen 1, it will work at 5Gbps.
If the plugged device is 3.1 Gen 2 or 3.2 Gen 2, it will work at 10Gbps.

If under Windows works fine but not Linux, then it is a driver issue.
Please try with the Windows system first.
If Windows works, then we can confirm the hardware is working fine.

I have now deleted all of the hostility from this thread and re-listed it. If you two cannot behave, then I’m closing the thread, okay?

I am saying the truth, he hijacked the thread with his argument that the BRIO is USB 2.0

21

Stop it now with the finger-pointing. Enough is enough.

You obviously have a disagreement on the capabilities of the device, so let the numbers speak for themselves, and then you’ll both know who’s right and who’s wrong.

22

You are absolutely right. Thanks for correction.

That’s is absolutely correct. I corrected myself above. I guess I was just overtired as I wrote it.

I cannot test if there is a general problem with USB3.1, since I have on all of my devices only USB3.0, so USB 3.1 Gen1.

Again correction:

You can see:

  • bcdUSB 3.10 (means USB 3.1 → USB 3.1 Gen2)
  • It can 10Gbit/s:
      Speed Attribute ID: 5 10Gb/s Symmetric RX SuperSpeedPlus
    bmSublinkSpeedAttr[3]   0x000a40b5
      Speed Attribute ID: 5 10Gb/s Symmetric TX SuperSpeedPlus
    bmSublinkSpeedAttr[4]   0x00e00026
  • But the device supports only:
    wSpeedsSupported   0x000e
      Device can operate at Full Speed (12Mbps)
      Device can operate at High Speed (480Mbps)
      Device can operate at SuperSpeed (5Gbps)

Therefore in that case, it can backwards on USB3.1 to a 5GBit/s connection. Therefore I would exclude a general issue. I use the original cables.

I think it might be the cheap cable that cannot do USB 3.0 connection over USB 3.1, I will locate the original cable and test the port again. I made the assumption that USB driver will give it 10 Gbits because of the port but didn’t realize that the Web Cam has to be USB 3.1 Gen 2 capable too. It may be weird that the cable could do 10 Gbit but not 5 Gbit but it is the only thing I can imagine, maybe test the cable is actually a 10 Gbit with a device that is capable of that spec.

My first thought when I saw the Amazon link was it’s the cable… I’d never buy something like that from Amazon, this article is an extreme example of why not, but you have to be careful with anything on Amazon that can be faked, especially electronics. But then it worked at 5 Gbps so I assumed you got lucky and the only part of the device->cable->port chain left to check was the port itself.

The reply you got from Gigabyte is correct, but a Linux driver issue is unlikely because something like that would have been spotted by many people. I’d bet that whatever USB controller is on that Gigabyte motherboard is also on motherboards from other companies. So yeah, if you have the original cable definitely try that.

@megavolt No worries, I blame the USB-IF and whatever drugs they were taking when they came up with that 3.x naming scheme. I think they realised this might not have been a good idea when it came to design certified logos… those don’t mention 3.x at all, just the speed :joy:
