Points towards flaky front ports imho or long shot a setting that has reduced the power going to the said ports.

I am more hardware than software so need to leave you with Malcolm now.

Good luck.

 

Thank you again for your time and help!

 

It does not appear to be a power issue. If the much more power-hungry external drive (900mA) works and the webcam (500mA) does not, it would not appear to be a matter of insufficient current. I, too, am at a loss to explain it.

 

Hi again, sorry to bump this thread but I just wanted to post a quick update. I found an old 2.0 unpowered USB hub that quite frankly I'm surprised it ever worked at the time I brought it from Poundland, let alone now. Anyway, I thought I'd see what happens if I plugged it into the front ports and it recognised as a 2.0 USB hub. I then plugged in the camera and to my surprise, heard the USB connected beep sound. Opened the Camera app and it was indeed working fine.

USBTreeView also detected it correctly.

I'm not sure if this sheds any more light on the issue, but I found it interesting at least to share.

Very odd. I don't think it sheds any light, it actually just adds to the confusion ... ;-)

It's just one of those things that makes you say "Hmmm.". ;-)

 

Can you post the brand and model name or number of just the main webcam concerned.

I wondered if it was a software problem, but as mentioned above, it works fine when I used the rear USB hub.

What port are you using on the rear, one of the black USB 2.0 ports or one of the faster USB 3.2 ports.

 

No problem and thanks for the reply. The webcam is a Logitech C920 Pro. The rear port is one of the USB 3.2 ports. The front panel ports are blue 3.1.

Thanks again!

 

The webcam is a Logitech C920 Pro.

If I recall correctly, that model webcam is USB 2.0 and recommends using a rear integrated motherboard port instead of using a front port.

I just checked, and it has Logitech Capture software for Windows 10, but not for Windows 11.

 

Not very helpful of me I`m afraid but I would have to say that being that both sets of ports are the faster 3.1 and 3.2 type it looks to be that it may well be the font ports have been damaged in some way.

Noticed your camera says Windows 8 or later, have you installed the Windows 11 chipset drivers and have you noticed that there were USB 3.1 drivers only for Windows 7, the latter which suggests that later OSs own generic drivers are all that is needed.

 

Any suggestion is helpful, I really appreciate you offering some ideas.

My fear is that I've damaged them in some way, but it's very confusing why other devices work and charge through them if so.

I've installed a bunch of Logitech stuff - camera settings (from W10) and G-Hub for W11, but neither made a difference. I couldn't see anything specific to drivers on Logitech's site.

 

Re-read post #5.
I added a comment to it about the same time you replied back.

 

Ah yes, apologies I did not see the additional comment before I replied. I have installed the Capture software too (at the time I read elsewhere that it was still compatible with Windows 11). But as I say, it's confusing why it works on a USB 3 port via a hub connected to the back.

 

Sure thing. I don't know if I can post a direct link to the one on Amazon but if I can, it's this one: https://www.amazon.co.uk/gp/product/B00VK9PRIU

 

Thanks, your hub is both backwards compatible and powered, the former means that it supports your USB 2.0 device and the latter means that it can support the power requirement of the camera whereas the front USB ports rely on the power provided by the front panel header on the MB which is somewhat lower than the hub.

To test the above theory, try the camera connected directly to the USB 2.0 ports on the rear of the PC, note the outcome, connect the camera directly to one of the USB 3.2 ports, does the camera still wok when not supported by the powered hub.

 

AFTER trying the suggestions above
I would draw your attention to the following
AMD® B450 Chipset y
1x USB 3.2 Gen2 (SuperSpeed USB 10Gbps) Type-C port on the back panel
1x USB 3.2 Gen2 (SuperSpeed USB 10Gbps) Type-A port on the back panel
2x USB 3.2 Gen1 (SuperSpeed USB) ports available through the internal USB 3.2 Gen1 connector
6x USB 2.0 (High-speed USB) ports (2 Type-A ports on the back panel,
4 ports available through the internal USB 2.0 connectors)

AMD® CPU
4x USB 3.2 Gen1 (SuperSpeed USB) Type-A ports on the back panel
You can see this layout on page 21 of your motherboard manual
E7B89v1.1.pdf (msi.com)

Therefore you will see that the front ports are controlled by the chipset

Referring to the BIOS may I presume that you did NOT install the BETA BIOS
Beta BIOS provision should NEVER be installed except for testing purposes - on a test computer.
I have long thought that some motherboard manufacturers do not make this clear enough on their download provisions
The latest BIOS is
AMI BIOS
7B89v2J
2023-07-11
17.87 MB

THE BETA version was
AMI BIOS7B89v2J2(Beta version)
2023-06-09
17.87 MB

There is a more recent chipset driver than MSI list but I need your system spec as explained at the top of your discussion please

Please click the link below for your operating system to download the TSG SysInfo Utility. Click on "Save File" then double-click the file to run it. Copy and paste the report in your initial post. Windows 7 and later (downloads a file named tsginfo.exe) |

So in summary
Check which BIOS you have if it is the BETA flash to latest
Post system spec please

and if the previously suggested tests etc and the BIOS flash do not fix it then when you post the spec I will confirm the chipset download for you

 

Hi, thank you both for the latest replies.

I've tested plugging the webcam directly into both the same USB 3.2 port that the hub is connected to and also one of the 2.0 ports. Both detected the camera without a problem.

I've just flashed to the BIOS as suggested (from 2.I0 to 2.J0), but still no joy on the front ports.

Here is the output text from TSG Sysinfo:

Thanks again everyone for your help!

 

1. I cannot see the possibility of the over current warning - having reduced power to the front usb ports
Although depending on how those ports are connected across the intricacies of the circuitryof the board I suppose it is a slight possibility

2. The camera is listed as 5V 500mA
which if you still have it is shown on the label attached to the usb lead.

3. Those front panel usb ports, which you say are blue are presumably connected to the usb 3.2 header on the board and should provide up to 900mA
Please see your manual page 32
Two headers on the board for front panel ports USB 2 and USB 3.2

4. WHICHEVER the front panel USB is connected to check CAREFULLY that the lead is fully connected to the header. THIS is expecially important if you have during maintenance or when connecting that CPU cooler - stood any chance of disturbing the connection - the fact that lower power devices work OK does not mean that - there is not still chance that the connection is faulty

5. You do not need the chipset driver from AMD there are no changes to the driver from the version on the MSI site that effect windows 11.

6. What is shown in device manager when tghe camera is connected
The fact it is not recognised on the notifications of 11 - does not mean that there will be no entry in device manager - even if for only unrecognised device.

7. IF nothing is shown in device manager and the cherck revbeals nothing with the connection
Download USB Tree View
USB Device Tree Viewer (uwe-sieber.de)

extract and run and see what if anyhting that shows for connection of camera.

8. UNLIKELY as it is with BitDefender Free version which as an aside you do NOT want to use on 11 - stick with the free included windows security and its Microsoft Defender - check in BIT DEFENDER if it is included in the free version - WEBCAM protection
What is Bitdefender Webcam Protection and what can it do? - Bitdefender
As I say very unkikely as it works OK in other USB ports, but worthwhile the check.

 

Further to the above on USBTreeView on the options tab set to show
expand empty ports
expand empty hubs
expand new devices

and clicking any port hub or device in left pane will show full description on main pane
and you can access device manager from the USBTree View GUI on tools tab

 

TheBoy
I am online as you can see by the green dot next to my name
I see you are as well so any questions please ask and I reply on receipt of them.

 

Thank you, yes I will. I am just running through USB Device Tree now and potentially something interesting. If I start the application with the camera plugged in, I get a yellow exclamation with the label 'Unknown Device'.

If I remove and reinsert the camera, then the port shows nothing (after hitting refresh).

Curiously, if I plug something else into the other front port and refresh, it then shows up again as an unknown device.

Should I copy and paste the full details displayed on the unknown device port when the camera is plugged in?

I should also say, that when the camera is plugged into a 'good' port, it shows under imaging devices. However when plugged into either of the troublesome ports, as far as I can tell, nothing shows up at all.

Oh yes, regarding Bit defender. I'm not sure why that showed up in the info as I don't have that installed. I do however have Emsisoft Anit Malware, so maybe that gets mistook for Bitdefender? Either way, I have tried disabling protection and it didn't make a difference.

Thanks again!

 

Have you checked carefully the connection to the board header

 

I haven't checked again just yet as I didn't want to restart my PC until I had looked at the other information. I have checked previously though, but will do so again now! I will report back ASAP.

 

Everything seems ok connection wise on the board and on the ports themselves.

 

Cheers
Going back to USB Tree View
Identify the root hub for the front ports
you will know which it is as it would show on the USB View as Unknown device

with the camera NOT connected and using the left pane of the view
right click the hub NOT the port and click safely remove.
if you get an error it is because you are not running as admin
File tab
restart as admin


Close all open windows
right click on taskbar the start icon
hold mouse on shutdown
hold down shift key and click
shutdown

RECONNECT camera

power on wait for notification to appear re hub and check what is now showing in USB TREE View or device manager

 

Further to the above and if it has not solved anything

he second is that I plugged in the USB connection from a replacement CPU cooler into one of the open USB headers on the motherboard and when I booted up, got a ‘USB Device over current status detected’ warning that automatically shut down the system

to which USB header

AND to which USB header are the front ports connected

There are THREE headers on the board
2x USB 2.0 connectors (support additional 4 USB 2.0 ports)
1x USB 3.2 Gen1 connector (support additional 2 USB 3.2 Gen1 ports)

 

Cheers
I am pleased we have made some progress
However you are correct -I regret to say
possible solutions have expired as far as I can see.

As my colleague Flavalee mentioned a lot earlier in the thread the spec for that webcam is USB 2
C920s HD Pro Webcam Technical Specifications – Logitech Support + Download

USB Protocol

USB 2.0

However the front usb 3.2

1x USB 3.2 Gen1 connector (support additional 2 USB 3.2 Gen1 ports)

should of course be backward compatible and as you say it worked before in them.

and more to the point although the camera is shown as usb 2.0
the support page from logitech says
+HD Pro Webcam C920 and USB 3.0 compatibility

Your Logitech Webcam C920 is fully supported with USB 3.0.
NOTE: If the color of the USB port you have the camera connected to is blue, it is most likely USB 3.0.

What they actually mean is that it needs 2.0 - but will work with backwards compatibility to 2.0 on 3.
as explained here.
Webcams 4: Hunting a USB 3.0 Webcam – Graves On SOHO Technology (mgraves.org)

Sorry again I could not solve it for you.

 

Hi, apologies for not being able to update sooner.

I tried removing the hub as directed and unfortunately, still have 'Unknown Device' showing when the camera is connected.

I have the front ports connected to the JUSB3 header which I believe is the 3.1 header. I have a Corsair Commander Pro plugged into JUSB2 and I attempted to connect the USB connection from a Prism Wraith cooler to the JUSB1 header which I think are the 2.0 headers.

 

I apologise if this has been covered but I hope you will realise that it is now a bit detailed on which configurations have been tried
HAVE you please tried connecting your powered hub to a front USB port
and then connecting the camera to one of the hub ports.

Also could you please clarify if this

the confusing part is that the ports otherwise seem to work fine – flash drives show up and they will charge a phone.

is still the case, with USB TREE VIEW running

 

I've just tried using the powered hub in the front ports and then connecting the camera and it worked fine. USB Tree showed the correct full name of the camera in the port.

When I plug a USB flash drive or a phone into the front ports, USB Tree is showing the name of the device correctly.

I also remembered that I have a USB voltage output display device. When I plug that into the front ports, it shows a steady 5v. I don't know how reliable those devices are (it was only a few pounds several years ago) but thought it was worth mentioning.

 

I also remembered that I have a USB voltage output display device. When I plug that into the front ports, it shows a steady 5v.

It's not so much the voltage as the current. 5V is the standard for USB, but the current available ranges widely with the USB standards. That determines the available power. Power is voltage times current (P=IE)

 

Ah I see, re the voltage tester and it's usefulness in this situation.

To clarify, yes the flash drive works fine in the front ports (same with charging a phone) without the aid of the powered hub.

One other thing I just thought to try was plugging in an external hard drive that says on the back it uses 5v 900mA. Again, I'm not sure if they actually draw that full amount of power, but I'd presume it a good sign at least? This also worked fine showing the drive in Explorer and also correctly in USB Tree.

Thank you again for your continued help, I realise that possible solutions now are likely to be wearing thin.

 

Thank you again everyone for their help and information. Frustrating we couldn't get to the bottom of it, but I will report back if I ever find out what the problem was or if it magically starts working again!
