    Rampage V Edition 10 Motherboard USB 3.0 & 3.1 Disconnection Issue

    "UPDATE:

    Its been almost a year, I forgot to post an update. I took my motherboard to our regional asus service center. They found out that the asmedia usb 3.0 controller itself was faulty. There wasn't any issue with driver or windows 10. The usb controller device was causing the issue.

Everything seems to be fine now with the z390 platform."

    Rest of the settings are left Default or Auto. I've been using this Overclocking settings since late 2016, its been almost 2 years. I spent weeks finding the most optimized manual overclocking settings for my build, so I can confirm that this is the most optimized settings for my CPU and Motherboard.


    ISSUE: For the last couple of weeks whenever I connect a device to any of my Rampage V Edition 10 Motherboard's USB 3.0 or 3.1 port the device randomly disconnects for a few seconds then reconnects back automatically in medium or high stress. For example if I connect my keyboard and mouse to my motherboard's back USB 3.0 or 3.1 ports to play games, whenever there's an intense moment full of objects & effects and the CPU & GPU gets a lot of load both the keyboard and mouse stop working for a second or two, even the LED's of the peripherals goes off (Specially ROG Claymore's) and on again while it reconnects. I play competitive games like DOTA 2 & PUBG and believe me this disconnection issue has been the main reason of my deaths and loses since it started to occur. If I connect my gaming speaker to one of these ports whenever it disconnects the sound of my speaker gets distorted and doesn't get fixed until I pull the USB cable out of the motherboard and reconnect it manually. Note that my speaker is a digital USB speaker, so there's no other way that can cause distorted sound.
    I couldn't concentrate on my works, play competitive games or do anything with my PC ever since it started to happen. Its been really frustrating for me, I didn't know what's causing it so I started troubleshooting. I tried connecting my devices to every single USB ports and this is what I found:

    1. The disconnection issue only occurs if I connect them to motherboard's back USB 3.0 & 3.1 ports marked on the picture below (Top four USB 3.0 and the two 3.1 Type-A below them)

    2. The Keybot and USB BIOS Flashback ports (marked below) on the back which are USB 2.0 I assume are completely OK. The disconnection Issue never happens if I connect my peripherals such as Keyboard, Mouse or speaker to these two specific ports.

    3. I also found out that the Front USB 3.0 Ports of my case are also OK. The disconnection issue doesn't occur if I connect my devices and peripherals such as mouse, keyboard and speaker to the front USB 3.0 ports. Note that my case has 4 front USB 3.0 ports and they are connected to 2 of my motherboards internal USB 3.0 ports.

    Note that sometimes during the disconnections process my entire PC gets frozen and I have to shut the PC down by holding the power button.

    STEPS I'VE TAKE SO FAR TO SOLVE THE ISSUE: First of all I disassembled everything from my case and created an open bench setup without the case to analyze the issue. I thought it may have been caused by a driver, firmware or windows itself, so these are the SOFTWARE BASED STEPS I tried:

    1. Disabled USB selective suspend settings from advanced power options.

    2. Unchecked the "Allow the computer to turn off this device to save power" option of all USB Root Hub including USB 3.0 and all USB devices from the device manager.

    3. Reinstalled every single driver separately/one by one which includes Graphics Driver, USB Driver and other drivers that I mentioned above, restarted my PC after every installation or uninstallation process.

    4. I tried disconnecting all other USB devices except mouse and keyboard. I connected the mouse and keyboard to motherboards USB 3.0 ports. The problem was still occurring.

    5. None of the steps above solved the problem so I tried installing fresh windows 10.

    6. After installing fresh Windows 10 I just installed the nvidia graphics driver (as x99 build doesn't have internal graphics) to check if its caused by other drivers. The problem remained unsolved. Then I followed all the steps mentioned above again, still no luck.

    7. Tried disabling OC and loading default settings from BIOS, tried disabling USB xHCI controller from BIOS, tried enabling XMP and Auto OC settings from the BIOS, nothing solved the issue.

    8. Note that disabling OC from the bios and loading default settings temporarily solved the problem but it still occurred once or twice if I work on my PC for 5-6 hours straight. Then again if I have to disable OC whats the point of buying this motherboard? Even right now my keyboard just disconnected while writing this post althought everything is set to default from BIOS.

    These tests confirmed that the problem wasn't caused by any software, firmware, OS or driver. So then I went for these HARDWARE BASED STEPS:

    1. At first I tried booting with a single 8GB stick of Memory.

    2. It didn't solve the issue, so I started to swap and boot with every single RAM using every possible port individually, it took my entire day but the results were the same.

    3. I tried running Windows Memory Diagnostics with every single RAM stick individually and then with all 4 together. The app didn't find any memory related issue.

    4. My tests eliminated the possibility of the RAM being the cause of the problem but I still boot my PC with a single RAM stick just to be safe.

    5. Then I swapped my Nvidia Zotac 1080Ti AMP Extreme with an AMD Sapphire R9 380x after uninstalling all nvidia drivers using DDU. It didn't solve the problem either. So GPU wasn't causing it.

    6. After that I removed my NVMe SSD and tried booting my PC using a completely new SATA SSD with new fresh Windows 10. Tried all steps mentioned above, nothing could solve the issue. Which means the issue isnt caused by NVMe or SSD either.

    7. I swapped my Cooler Master V850 with my cousins V750 to check if its a PSU related issue, turns out its not.

    8. I swapped my 2000VA digital UPS with another one, I also tried connecting the PSU directly to my wall without any UPS.

    9. The only two things I couldn't swap are my intel core i7 6800k processor and NZXT Kraken X72 cooler as I don't have any spare cooler and none of my friends that I know uses x99 based processor. I assume the problem can't be caused by a CPU or a Cooler.

    As my last hope I took my entire rig including the motherboard to ASUS Authorized Local RMA Center of our country which is run by Global Brand Pvt Limited. They cleaned the Motherboard very carefully and booted the PC with my peripherals and their test bench PSU. Even thought the PC freezed and shut down a couple of times due to their lower watt PSU but the USB issue didn't occur for a single time. It happens randomly if I keep the PC turned on for a long time, but I could only stay there for a couple of hours. We still tried to recreate the issue within the short time but as it was time to close the RMA center I had to leave. I thought the issue was caused by the dusts they cleaned, so I returned home happily thinking that the problem has been solved. Just when I was about to relax and get back to work using my PC the disconnection issue occurred again. It happens so rarely (like once or twice a day) and randomly that I'm not feeling comfortable taking my PC to RMA one more time and waste their time. What if the issue doesn't occur again? As I'm a PC enthusiast I don't go to RMA very often and I always try to resolve my issue myself, so that would be really embarrassing for me if the problem doesn't occur in front of them again. Now here I am seeking for your help. If there's any possible solution that I haven't tried yet please do let me know, I'd really appreciate that. I'm also trying my best to record the disconnection issue using my tripod and camera.

    Hey brother, I know exactly what you are talking about since I did have the same problem. But I found a solution since nobody in ASUS and not too many are talking about this issue. Let me know if you still have the issue and I'll explain the solution to you.

    The problem has to do with either windows 10, can't tell for sure since i havent tried my system on windows 8.1 or 7 other than windows 10 where i was getting the disconnection problem, or it could also be a buggy asmedia driver that happens to be misbehaving with a windows service called swusb. You have to stop it and disable it. The service is supposed to switch the usb 3.0 to 2.0 and back. For some reason the usb ports switch from 3.0 to 2.0. It happens randomly and for no reason, the usb devices connected to the usb asmedia controllers aka all the ports on the back panel, stay disconnected. I would also recommend getting an ext usb 3.0 hub. You should have two 3.0 ext ports on the motherboard. One for the front of the case and another for the back. Asus messed up. The ports on the back panel of the motherboard that you highlighted above are asmedia and they are faulty. The intel usb 3.0 controllers are on the ext motherboard ports. But like i said, just open services, and look for swusb service, stop it and disable it. That should fix the disconnection issue.

    Hi irahat,

    I advise you first to update your ASMedia USB 3.x drivers then your Intel drivers :

    - Here are the latest drivers 1.16.54.1 for ASMedia USB 3.x : https://mega.nz/#!lYsDyRTI!AwLasthHn...TKitnSCx2E3M_w

    - Here are the latest Intel drivers for Rampage V : https://rog.asus.com/forum/showthrea...SATA-(Z97-X99)

    You can also update your Intel ME (Management Engine) firmware here : https://rog.asus.com/forum/showthrea...l-ME-(Z97-X99)

    That is the very first thing i did without any luck. Like the the guy above said it happens at random, like very random, the usb drivers would stop working, reset and switch to 2.0 reconnect and then act weird and all the devices connected like mouse and keyboard would all turn off. Let me point out again, the problem is present only with the asmedia usb controller ports on the back panel of the motherboard, intel controller usb ports work fine. The problem is tha every single usb 3.0 and 3.1 port on the back panel of the motherboard are asmedia. If you want to use the intel usb controller youre limited to the 4 ext usb 3.0 ports on the bottom of the motherboard which are for the front panel usb ports of the case and getting an extra usb 3.0 ext ports for the back. The only work around for the asmedia usb 3.0 ports to stop disconnceting is to turn off the windows service swusb. On windows search type services and open it. Then scroll all the way down and look for swusb. Stop it and disable it.
