Last month, we reported that AMD had been made aware of many users experiencing intermittent connectivity issues with USB ports on its Ryzen 500-series motherboards. Requesting that users with any USB drop-out issues reach out directly to them, AMD has now released a statement confirming that it's planning to release a firmware update via a new AGESA update.

A post on Reddit by the official AMD account, u/AMD, has revealed that AMD will distribute a new firmware update named AGESA to its motherboard partners within a week. AGESA (AMD's Generic Encapsulated System Architecture) is AMD's primary base on which motherboard vendors build their firmware around. This means it's likely that an update alleviating users with problematic and intermittent USB issues isn't far away.

AMD's official statement on its new updated AGESA reads as follows:

We would like to thank the community here on r/AMD for its assistance with logs and reports as we investigated the intermittent USB connectivity you highlighted. With your help, we believe we have isolated the root cause and developed a solution that addresses a range of reported symptoms, including (but not limited to): USB port dropout, USB 2.0 audio crackling (e.g. DAC/AMP combos), and USB/PCIe Gen 4 exclusion.

AMD has prepared AGESA to deploy this update, and we plan to distribute to our motherboard partners for integration in about a week. Customers can expect downloadable BIOSes containing AGESA to begin with beta updates in early April. The exact update schedule for your system will depend on the test and implementation schedule for your vendor and specific motherboard model. If you continue to experience intermittent USB connectivity issues after updating your system to AGESA, we encourage you to download the standalone AMD Bug Report Tool and open a ticket with AMD Customer Support.

Randomized USB disconnects can present many issues for a variety of users, with reports of USB capture devices cutting out while recording and problems with VR headsets that primarily rely on its power from USB ports. This also stretches to mouse and keyboard input issues which can also cause an inconvenience to end-users. 

Despite AMD admitting that there is an underlying issue surrounding USB ports on its Ryzen 5000 and Ryzen 3000 processors when used with 500 and 400-series motherboards, it hasn't gone into details about the fix. They believe they have identified the root cause of the issues, and the new AGESA firmware should begin rolling out sometime in April.

    Exactly! People should wait a CPU generation when PCIe 4.0 was just released.... Now if you'll excuse me, I'll go plan my DDR5 Ryzen 6950X build.

    Are you seriously blaming the end users? It's not like they are using beta products, this is not the fault of "early adopters"

    I routinely copy vast amounts of data from 4K Dash Cameras to the 14TB Hard drive, albeit over USB 3.0 which I surmise is immune to the bug from reading a few comments.

    I have two USB 3.0 hubs that I run most of my peripherals off of, but my mouse is plugged into a USB 2.x port. I do have a legacy Canon scanner that plays better with the USB 2.x ports for whatever reason.

    The only oddity I've noticed is that sometimes when idle, my Kingston USB 3.0 card reader will randomly disconnect and reconnect giving that disconnection/connection chime that you get when plugging or unplugging in a device.

    I am going to try flashing the firmware on that, looks like Kingston has an update, and I can't recall if I have applied it already or not.

    The only other thing that bugs out sometimes is copying files from an iPhone (XS, 5s, and 12 Pro Max) over USB 2.x and 3.x For some reason 2.x seemed more stable. I've attributed it to a few possible things not USB (but that is possible contributor to the issue as well): Old school Phenon II 1090T system with a 4 TB storage drive with known Windows 10 issues (could use a clean install) connectivity drop out or timeout errors. Issues with the Apple drivers and ITunes update and autobackup running in the background preventing DCIM folder from displaying contents--possibly tied to Antiviral software "seeing" newly connected drive and doing a background scan automatically on the drive as well.

    But for daily use (play stupid amounts of world of tanks and other games, internet browsing, document editing and general use) I couldn't be happier, with the exception of the few occasional bugs above. They don't happen consistently either.

    The PCIe 4.0 Sabrent Rocket drive has been amazing...was nervous about that at regrets.

    AMD is pushing a lot of boundaries lately. That comes with risk. Intel used to push boundaries that had consequences too, going back to the original Pentium P54 CPU FDIV bug, the recalled Pentium III 1.13GHz, the recalled i820 chipset, and the legendary Cougar Point (P67 chipset?) SATA3 bug that literally corrupted hard disks.

    As it turns out, the later is very similar in timeframe to AMD's USB issue. It wasn't present at the beginning of the chipset launch, only to creep up later (~6 months) and some suspect, like Intel's chipset, this could be a silicon degradation issue. Fortunately AMD believes they can fix it with software - Intel couldn't. Perhaps AMD can tune the attenuation or voltage of the chipset to pad for voltage drops or signal issues, whatever is causing the drop outs.

    and you probably don't even have an AMD rig, just the typical useless internet posts
  • DabuXian - Wednesday, March 17, 2021 - link

    Glad they (supposedly) fixed it, my peripherals losing connection every few hours for a few seconds is mildly annoying. Kinda disappointed that such a bug existed in the first place, but oh well, better late than never I suppose.

    Just set up a 3700X on a Asus WS x570 ACE to test. Everything seemed fine except wireless mouse seemed wonky (like it was just at edge of reception and would sorta work, but sorta not). didn't think anything of it because it was a cheapo USB wireless mouse and I was just setting up windows not doing anything that really needed mouse preciseness. Had everything installed and went to copy from files to faster USB 3 flash drive (in a USB 3 port of course). Used File manager, and the graph that shows you how fast you are transferring the file looked like a 1/2 sine wave. It started at 0 ramped up to 60MBps for a few seconds, then quickly dropped to 0 and stayed at 0 for 10 seconds. repeat over and over until the file finally completed way-to-long later. It would do this on any of the USB3 ports. Tried flash on another PC, no problem, then tried mouse on another PC and got 2x the range without issues. Did some research on the internet and discovered others having USB problems.. Did BIOS upgrade to latest.. Still problems.. Said screw it and put my 9700K and motherboard back in. I don't use the USB a lot, but I expect them to work perfect when I do. I got plenty of hassles in my life and dorked up USB ports aint going to be one of them! 3700X is just a side grade to the 9700K anyway as I just wanted to try it out.

    A lot of this has to do with the board, as well. Most users aren't having these sorts of issues... especially on Zen 2 and earlier. I've got a 3600 Ryzen, with the latest stable BIOS everything is smooth sailing... and this doesn't include the "fixed" AGESA the article mentions.

    Also the problem seems to be exacerbated if you're using a 4.0 GPU, especially the latest gen Nvidia cards. I've seen a lot of users that only had issues with their 2.0 ports, or only with hubs. So the issue isn't a simple one, and most users aren't having problems. Still, it's good to see them trying to tackle it.

    I have a gigabyte b550 aorus master with AMD 5800X cpu used as a Linux based music server. I have updated to the latest F13e bios with AGESA ComboV2 the usb DACs are fine when playing pcm but if we turn on pcm upsampling to dsd we get serious drop outs and have to reboot the system. The higher the processing load (dsd128, dsd256, dsd512) the faster the drop out. With dsd128 we can reset the usb and carry on running. If our issue us not addressed by agesa then I will looking at replacing the AMD with an intel equivalent.
