Hi, I just bought this B550m PRO4 motherboard, and it worked fine for a few days. Now windows is making sounds and sending notifications that a USB device is connecting and disconnecting. I've unplugged ALL USB devices (even motherboard connectors) and the same thing happens. It never stops. Any help? |

| Ok tried in both windows and linux and the same issue. Tried updating the bios and still the same issue. Bios is very sluggish now and i have to wait around 2 seconds before being able to select the next item. |

Hello everyone. I have this same issue. I've tried everything from disconnecting all devices, searched on bios to disable usb but i couldnt find any option to do that. I was thinking on reinstalling windows but reading your comments I think it wont solve this issue. Please ASROCK say something! |

I'm on my second board now, it worked for around a week. Now it's broken again with the same issue. I'm going to send it back again and go with some other brand. When this happens you can't even navigate the bios because the built in usb controller keeps disconnecting/reconnecting. ASRock is no help, and this board is junk. Hope you didn't send in the rebate because you can't return it then. If you figure out how to resolve this please let me know otherwise it's going back in 2 days. Good luck. |

I am having the B550M Steel legend board, seeing the same issue as well, works well for a few days before seeing the USB Descriptor failed issue. Tried reinstalling windows, tried unplug all USB from the board, totally out of idea. Really regret getting this board..

| I've done some reasearch and it looks like this could be related to memory issues. Can you try setting your memory really low like 2133mhz and see if it still happens? I'd try it but i already sent mine back. I can't game like that. |

| UPDATE: I might have found the root cause of the usb disconnecting issue, it was the USB Type C port!! I tried connecting the USB C to my devices (Phone and tablet), and there it goes, the disconnecting noise stopped but on the Device Manager, it is still showing the same USB Descriptor Request Failed reason. I think ASROCK need to provide the USB Type C driver for windows 10. |

That's strange. I did notice not very many of the b550 boards have the USB c port which is one reason I purchased this board. When you go into the bios is it really slow and sluggish when navigating the menus? If so it's probably not the driver as the USB controller is connecting and disconnecting even when in the bios. Did you update the bios to 1.10? Just curious because that's the first thing I did when I set up my computer. Then a week later it was broken. I'm surprised there aren't more people having this issue. Maybe it's just a matter of time. Mine did work perfectly for like a week. |

https://www.reddit.com/r/ASRock/comments/hz45hi/usb_noise_spam_issue/ Seems asrock told others it is a bad board. There silence and lack of support here is really disappointing |

Yes, I have upgraded the BIOS to 1.10. TBH, I thought updating the BIOS would resolve the USB issue but its NOT. About the sluggishness of the BIOS, previouly I thought it was due to my peripherals connected to the USB 3 port then I tried to switch to the USB 2 port instead but it doesnt help to solve the sluggishness. After that I browse around the BIOS menus, and I have found out it was due to the HD support of BIOS. Simply change the BIOS resolution to a lower one will solve that.  Well, this is my 1st pc build and 1st motherboard , I will live with that USB issue for now, until I switch to a better motherboard in the future. Definitely will not be getting another ASROCK!

| Going off of a previous reply talking about the USB-C port, I fixed both the USB errors and BIOS slowdown by having a USB-C device plugged into the port at all times. |

| Hi, I am currently using B550M steel legend and also getting this issue. No luck for me.I tried to plug in USB-C port but still getting this issue but probably is the USB-C port issue cause the device I plug in always disconnect and connect. |

| I guess I spoke too soon, the problem is there, but at least it's not 24/7. Sometimes it goes away on its own, sometimes I have to disconnect and reconnect my USB-C device to stop it. I'm going to try what ASRock support told me to do and report back. |

I mean it didn't work but here it is o Please disconnect ATX Power supply connect (24pin) from the mainboard. o Remove the CMOS battery from the m/b o Located the CMOS switch on the back of I/O panel. press and let go for 7 times. o After 3 minutes. Please restore the battery, back to default position. Reconnect ATX connector. |

I'm having the same issue happening while I'm typing. I can find a unknown USB device keeps connecting and droping. the device location is Port_#0005.Hub_#0001 In my case, the problem happened once before but disappeared after rest overnight. I highly suspect that this is a hardware defect. I have to disable the win10 sound notification for device connect and disconnect as a temporary solution. |

| What cpu are you guys running? I'm using a newryzen 5 3600. I wonder if it's possible a cpu defect could be causing this. I tried two of these motherboards both worked good for a few days then crapped out. What are the chances of that happening. My suspicion is the cpu is defective and frying the usb chipsets. But who knows, No one will respond here. |

Sorry forgot ram and power supply: Ryzen 5 3600 16GB (2x8GB) Corsair 3200Mhz CMK16GX4M2B3200C16W ver 5.32 EVGA 600W power supply Asus TUF 1660 Super I saw a review on newegg where they had the same issue as me, and i think they were using the same ram and CPU. But this ram was used in a previous build and it worked perfectly. |

| It's not a CPU issue, it has something to do with the USB ports themselves. I'm running a 3700X and still ran into this problem. I will say that even though it's still happening, it's happening way less frequently after following the steps CS gave me (that I posted earlier in this thread) AND plugging in something in the USB-C port. Apparently the USB-C thing doesn't work for everyone but it's helped in my case. |

| Believe it or not, one of the USB controllers is located on the CPU, and another is on the chipset. |

Oh I thought, this usb was only my problem. it's weird, currently I'm not having this usb problem. But One thing that i remember, my USB 3.0 Wi-Fi device will trigger the usb failed problem when plugged in into USB 3.0 port. And I also got a problem when switch to power saving mode when using Asrock motherboard utility (A-Tunning). Mouse was like very sluggish, slow to response. |

| Asrock should acknowledge the problem, as this is a ticking time bomb, and the fact they offered a rebate pretty much guarantees you can't return it or if it breaks after 30 days. Turning off the sound is not a solution, as it causes slowdown/lag while gaming as the computer thinks a devices is constantly being connected/disconnected. |

Hello, I have the same problem. I have an ASRock X570 Steel Legend. It worked normally for a few days and then the problems started. The UEFI bios is very slow with the mouse and keyboard. Both move very briefly every 2 seconds. Windows is constantly connecting and disconnecting the USB connection. UEFI takes over 1 minute to start. I was able to switch off XHCI support in BIOS version 1.9, then it got better. But then I no longer had a USB 3. This setting is no longer available in the new BIOS version. Sorry for my bad English. |

I have now got the system up and running to some extent. With the BIOS version 2.80 and my Ryzen 5 3600XT (Matisse 2), Windows still shows an unknown USB device, but it is not constantly connected and disconnected. But the UEFI bios itself runs very slowly. With version 2.60 I could deactivate under "Advanced"> "AMD CBS"> "Chipset Common Options"> "Chipset USB Configuration Options"> "XHCI-Controller0 + 1". When I activated controller 0 and deactivated 1 everything works very well. But then I no longer have a front USB. In version 2.80 you can no longer deactivate the XHCI controller. I hope for a UEFI update for the Matisse 2 (3600 XT) with working USB 3 ports and smoothly running UEFI. |

| I was wrong, after using Windows 10 for 30 minutes it suddenly started activating and deactivating USB again. Thats so bad. I have deactivated the controller in the control panel, but it cannot remain permanent. Please ASRock, correct this bug or I will send the mainboard back to the seller. |

I have a few items which seem to have a bit more traffic on USBs, and these seem to trigger the whole chain of events. I have some music hardware (more specifically a Focusrite USB soundcard and a Minibrute synthesizer). My way to reproduce has been to hog the system with the synthesizer, then after a while things start to go south. ASRock support _did_ reply to me, but I found it in my spambox, so one of these days I'm going to run through all the suggestions and will try to pinpoint the problem area. If you find more things, please keep me (and others) posted, as it's really a pain in the ass. It's much appreciated <3 |

Yes, it's all very annoying. My last ASRock board with an AM3 processor ran very well with no problems. The Steel Legend with UEFI version 2.80 delivers the following error when starting Linux: [0.003597] __common_interupt: 1.55 No irq handler for vector If I switch back to version 2.60 and deactivate the eHCI controller in the BIOS, this error does not appear. Then USB 3 is deactivated and front USB is also deactivated, but Windows and Linux are running very well. |

| These boards are all defective. I highly recommend returning and buy an asus, msi or gigabyte. It may be $20-$30 more but think about all the time you wasted on this asrock problem. They won't even reply to this forum to help. |

jmandawg, this is a community forum not an official support avenue. While yes, ASRock can and does reply threads here they do not see every post made on the forums. When the forums are not able to help you you need to make a support ticket to ASRock directly: https://event.asrock.com/tsd.asp The fact that ASRock does actually check in on the forums and try to help people here is one of the key reason I am a moderator here. -------------

So, what's the current status with this problem? Is it safe to buy a B550M Pro4 now? Was there a HW rev. update or a BIOS update to fix this? Or is it still unresolved? |

@Xaltar: Could bring the following to the attention of some tech at ASrock? It's seems like Gigabyte has the same USB disconnection problem with one of their B550 boards: https://old.reddit.com/r/gigabyte/comments/hrca2y/problems_with_b550_aorus_pro_ac/gcxg667/ At least two users were able to fix the problem by discabling C-States in the BIOS, which let the voltage drop too low in idle for the chipsets USB ports, resulting in repeated reconnections. Gigabyte has issued a new BIOS to fix these stability problems at least on Matisse systems. |

| I wanted to get in touch again on this topic. I was in contact with ASRock's support and they recommended that I send the board back to the supplier. I did that and have now received a new board. So far the BIOS has been running smoothly and Windows 10 has remained quiet. There is now version 3.00 on the board, I will not make a new BIOS update on it as long as it works. I was told it could be due to the AGESA drivers, but I can't guarantee that. |

Well, like everyone said it was the USB-C port. I plugged my WiFi usb receiverwith a USB-A to USB-C adapter into the USB-C port and everything is fine. The driver for that port (port 5) is now correctly installed. What a huge waste of time after installing new bios, chipset, etc. Hope they fix this and this helps someone else |
Posted By: quantummoon
Date Posted: 29 Apr 2021 at 1:58am
I can also confirm unplugging the adapter from the USB-C part is fine. The driver is still installed correctly. I imagine windows needs to install a driver for the USB-c port while something is plugged in. Will update if anything changes. |

Nope, after unplugging it started again. Keeping plugged in for now |
