Glucose Posted February 22, 2021 Posted February 22, 2021 AMD is aware of the issue, check out their post on Reddit Guess we need to start following the AMD updates now. Man, there are 1000+ posts in there with people with the same problems. I thought it wasn't as wide spread.
LeDoyen Posted February 22, 2021 Posted February 22, 2021 Gamers Nexus just covered the issue so maybe more people will report on it. But it's been going on for a long while without a word from AMD.
Baio Posted February 23, 2021 Posted February 23, 2021 The issue is not the Commander Pro attempting to draw to much USB power. The Commander Pro itself is powered by the SATA power cable. The has been explained time and time again, and is the internal USB 2.0 headers not supply enough power to adequately maintain device connections via the passthrough. The reason the hub works is it has supplemental power from the PSU which resolves the USB power issue of the header on the motherboard. Supplemental power? But also the CoPro has a USB and a SATA connection. Why USB hubs should provide more power? Baio
LeDoyen Posted February 23, 2021 Posted February 23, 2021 even when the USB port isn't working purely in power delivery mode, it still powers the CoPro electronics. Seems that's bugged on the latest AMD chipsets. Using the hub, there's no power cut on the USB side since the hub takes care of the power delivery that the motherboard fails to supply reliably. I believe the SATA power is only connected to the fan PWM, and RGB outputs on the PCB to deal with the bulk of the load.
BKGolden Posted February 23, 2021 Posted February 23, 2021 I have Corsair H100i RGB Pro XT and a Commander Pro plugged into my MSI Tomahawk B550 USB headers. The USB would annoyingly disconnect/reconnect frequently. I disabled global c-states (Buildzoid had same issue/solution) and that seems to have fixed the issue. No usb drops for several days now. Not ideal but hopefully AMD will fix the issue soon.

I believe the SATA power is only connected to the fan PWM, and RGB outputs on the PCB to deal with the bulk of the load. So - if I got it the right way - CoPro expects a constant minimum of power from the USB port, and the chipset fails sometimes to deliver it causing the disconnection. This is probably due to some energy saving mode of the chipset, the USB hubs do not have this modality and deliver constant power. But then why the CoPro keeps disconnecting/reconnecting? Doesn't it suppose to just disconnect? I'm just asking for couriousity, I've never had this issue. Baio
Mussels Posted February 24, 2021 Posted February 24, 2021 Hey guys, AMD are investigating USB dropout issues on X570 (and maybe B550) motherboards at a driver level - if you meet their criteria hit their support up https://www.techpowerup.com/278870/amd-acknowledges-usb-connectivity-issues-on-500-series-chipset-motherboards
Corsair Employee Corsair Notepad Posted February 24, 2021 Corsair Employee Posted February 24, 2021 The SATA power for the Commander Pro does not power the USB Pass-through. The USB port by is supposed to provide enough power over USB to establish and maintain that connection with the USB device plugged in.
Thunderpants Posted February 25, 2021 Posted February 25, 2021 Potential Solution Many people posting will be using HWiNFO to log and report on sensor info. There have been reports of conflicts with ICUE software / Commander Pro USB ports Try Uninstalling HWiNFO make sure the HWiNFO service is gone. Reboot and your disconnects may be gone! Thank you! This worked for me, although I only needed to quit the app to stop the disconnects. /cheers My Specs: Gigabyte Aorus Master x570 H115i Platinum Lighting node core

The USB port by is supposed to provide enough power over USB to establish and maintain that connection with the USB device plugged in. I just barely learned PC specs about a week ago, so please bare with me. I installed 6 QL120's into my rig last night using the Commander Pro and Lighting Node Core. ICUE is only recognizing the Commander PRO. Fans stay on a rainbow setting, and I can't change the RBG because the lighting node core isn't being recognized. The core is getting power through SATA, which is why the fans are lit up to begin with. But the core isn't listed in the devices section of ICUE due to faulty USB connection; this is basically what I got through the thread. I haven't done enough testing to see any other issues, the fans are running just fine, it's literally just not having the ability to change my own RGB lighting, correct? The external USB drive is the only way to solve, I take it. I'd appreciate any and all feedback. Asus Z490-V EVGA 3090 64GB G.SkillL intel 19-10900k 3.7GHZ

The only time i had one such issue was with a HOTAS that was overloading my USB port. it was blinking, and disconnecting/reconnecting. but that's a bit different since it was getting all its power from USB. I guess the answer may be hidden somewhere in the USB specs.. in case of connexion loss, retry after x seconds. The problem here is not the constant retries, it's the fact that the connexion is lost to begin with.
Sixstringmonk Posted March 9, 2021 Posted March 9, 2021 Just an FYI - installing a NZXT internal USB hub did not fix the issue for me. I know it's working for some folks, but it must not be a universal fix.
Afdam Posted March 9, 2021 Posted March 9, 2021 Same issue disconnect/connect sound and h100i platinum disappeared from iCUE fresh system installed only chrome and iCUE still don't see it and and sound is back but before I pressed update function I icue everything was spoton run out of ideas .

vivz Posted March 16, 2021 Posted March 16, 2021 [sorry for my bad english, I'll be clear as much as possible] Quick update on my usb disconnects on my B450 build (Ryzen 3600x - Corsair RGB Ram / Keyboard / Mousepad / Commander Pro / 4X HD120 fans & ST100 RGB Headseat stand), no fix here but interesting notes which can help some people. When I installed the NZXT hub, I still had usb drops but like 1 per weeks, still better than 1 every 30 minutes before the NZXT. After definetely uplugging the ST100, I never had disconnections anymore. I played like this for months and usb were ok, no more drops. Then one day , usb started to drop again, like every 15 mins. I did not change anything to my build (no iCue update for example) EXCEPTS the way I connected my devices to the back of my motherboard... I have 3X2 usb at the back of my Asus B450 Prime motherboard, every corsair devices are alone on every usb groups and disconnects came back when I moved my Corsair RGB mousepad next to my Corsair RGB Keyboard. When I moved my mousepad back on the "empty usb group" above and disconnections stopped. So no fix there, but I've been able to use my pc without usb drops with the NZTX hub, definetly disconnecting the ST100 and plug my corsair devices alone on each usb groups.. Just for info, I had the same corsais devices on my previous build (Asus Prime Z370 with Intel i3 8350K) and never had any issues.
Corsair Employee Corsair Notepad Posted March 16, 2021 Corsair Employee Posted March 16, 2021 Please refer to the pinned AMD USB Disconnect thread where we provide information from AMD related to these issues. This is a confirmed bug with the AMD chipset. https://forum.corsair.com/v3/showthread.php?t=204534
