[SOLVED] USB ports randomly disconnecting until reboot on Linux Mint 20.1

togamid · Post by **togamid** » Mon Mar 15, 2021 3:24 am

Hello,
on my Tuxedo Pulse 15 with Linux Mint 20.1, the whole USB2.0 branch randomly disconnects every few hours to a day, including the internal camera and the to USB2.0 ports. The USB3.0 port continues to work fine when that happens.I've already tried disabling autosuspend as suggested in viewtopic.php?f=49&t=287775&p=1593287, which seems to have prolonged the time it takes for the problem to appear, but didn't get rid of it.
The problem has previously occurred under Ubuntu, but seems to happen at a much lower rate if it still happens at all (didn't occur during 3 days under Ubuntu).
The USB ports work fine again after a reboot.

Thanks for your help.

You are not the only one seeing this issue Bluetooth and Webcam problem. That person is running Pop!OS 20.04 on an ASUS laptop and the messages are almost exactly the same as yours.

Does this seem to happen more often after using the webcam for extended periods? Maybe a heat related issue?

What does Tuxedo say about it? Guarantee case?

yeah, there are a bunch of reports of this problem I found (viewtopic.php?t=339335 , https://www.reddit.com/r/linuxmint/comm ... connected/ ), but none seem to have a definitive answer or a complete description of the problem which is why I made this post.
It might have something to do with heat or power draw, as I have the feeling that it occured more often when the camera is on (but that isn't necessary for the error to occur) and disabling autosuspend definitely made a difference. But I don't think heat is the only reason, as when I tried to provoke it under Ubuntu I left the camera running for some time and it didn't trigger.

Unfortunately, they only support Ubuntu, and the time it happened under Ubuntu I had a defect SSD too. That's why I tried provoking it under Ubuntu.
As I found this exact complaint by people with different hardware (ThinkPad L15 Gen1, Asus UM425I, ThinkPad E15 Gen 2 ), I think it's a combination of a software and a hardware problem (maybe some USB hub has an error?).

Yours has AMD Ryzen 7 4800H, ThinkPad L15 Gen1 has AMD Ryzen 7 PRO 4750U, Asus UM425I has an AMD Ryzen 4000 series processor, and I'm going to take a wild guess and say the ThinkPad E15 Gen 2 probably also has a Ryzen 4000 series, so I would consider the hardware to be similar rather than different.

Was your test with Ubuntu using the same exact kernel you were using with Mint?

Does your BIOS/UEFI have any settings available for xhci_hcd? I'm guessing it may not, but it's worth a check.

Unfortunately not. Ubuntu used/uses the kernel 5.6.0-1048-oem whilst Linux Mint is on the kernel version 5.8.0-44-generic. Should I install the 5.8 kernel in Ubuntu to test it or is it possible to install the 5.6 oem kernel in Linux Mint?

I could not find anything that seemed to be related.
Thanks for your help.

Yes, it is possible to install a 5.6-oem kernel on Linux Mint. I know of at least one person using that kernel because of some hardware issues, but I was not on the thread where he installed it. Here is the portion of that other thread where they discuss how to install the 5.6-oem kernel.

Keep in mind that is a lower number kernel than your current one, so Mint will automatically boot into 5.8. To boot into the 5.6, you will need to boot into grub and then go to Advanced Options to select the 5.6 kernel for booting.

The other thing to keep in mind is that it's my understanding that at least kernel 5.7.1 is needed in order to get the necessary graphics driver for Renoir. I do not know if there is something special about the 5.6-oem kernel that it has the driver. Were you running in software rendering mode when using Ubuntu?

Hi,

I'm seeing something similar with multiple systemd distros (including Mint) on the same hardware. Intel i5 CPU and the same 5.11.4 kernel.

USB3 ports disappearing during large file transfers (multiple ~100GB files).

File copies are perfectly fine using Slackware, Devuan and Artix Linux.

The issues seen here are on AMD Ryzen 4000 series and the OP is running the 5.8 kernel. That's not the same hardware or the same kernel as what you posted.

Additionally, the issue is with USB 2.0 ports disappearing. The 3.0 ports are fine.

There's no need to regress to kernel 5.6 in order to gain the benefits of the OEM kernel. (That OEM kernel 5.6 was needed for special audio firmware.)

Install the Hardware Enablement (HWE) extension. You'll keep kernel 5.8, which is a definite benefit to your Ryzen / Renoir GPU.

Open a Terminal (Ctrl-Alt-T), then copy-and-paste the following command...

Code: Select all

sudo apt install --install-recommends linux-generic-hwe-20.04

Reboot.

The HWE stack pulls in new hardware support that gets added to more recent and future releases of the kernel. It's intended to prevent the LTS (Long Term Support) editions of the kernel from falling too far behind the most recent releases for new hardware platforms.

PS: Confirm that Secure Boot is disabled in your BIOS.

The point of using the 5.6-oem kernel was because that was what the OP was using with Ubuntu when not experiencing these issues. The idea was to do an apples-to-apples comparison between Ubuntu and Mint by using the same kernel in both. That would determine if the difference was the kernel or some difference between the two operating systems. Tuxedo supports Ubuntu (and probably with the 5.6-oem kernel) and not Mint.

Having explained the philosophy behind the suggestion, it is possible your suggestion might help with the issue.

I have had and am now facing this issue with the USB's randomly disonnecting again. I had my system working great for many months without seeing any of this until last week with a possible update and etc. This issue with the USB's has been around since Ryzen and isn't on any specific version CPU and etc of Ryzen.

I am trying out the disabling autosuspend as well as I am now in the process of retracing my steps to prevent the USB disconnects and etc. Here is were I am now. I always follow 'Easy Linux Tips Project' pages and I came across this which is a step I remember following in the past few months (Especially Step 1 'PSU Idle Control'). https://easylinuxtipsproject.blogspot.c ... .html#ID27 Step 1 in their 'Fix system freezing trouble with AMD Ryzen CPU's' doesn't just pertain to CPU's and Freezes as it states. This can also prevent other issue across the system. It's your choice if you wish to do Step II in their guide. but be sure to backup/timeshift prior.

I am now in the waiting stage to see how this pans out as a solution. I will update as soon I see any results.

Update: So far since I posted the above I decided to remove the disable 'autosuspend' and test out the PSU Idle Control on it's own and allow the system to go idle and etc. Since then I haven't seen any usb disconnects after performing the PSU Idle Control changes in the BIOS. My system has been running straight for 9 hours and 21 minutes. I have been working with my system as well as allow it to be idle. I will continue to test this and see if this continues to be true.

I will now be switching the PSU Idle Control back to default to test this and see if I get USB Disconnects to occur again.

Update: March 19 @1:00PM
With PSU Idle Control Set to Default I had my first USB Disconnect
I am now testing with PSU Idle Control set to 'Typical Current Idle'. I will have it running for a full 24 hours or until a failure occur's.

Update: March 21 @11:45AM
I haven't had one usb disconnect since I set PSU Idle Control to 'Typical Current Idle'. Although I will still be testing this to make sure. But this is a positive note on my end. Hope it works for others.

Well I just wanted to put an update on here with my progress. I have had great success with the above instructions until today. Some how my Bios reset itself to factory. I didn't know it until my usb ports all stopped working at the same time while I was using my pc and active. I went into my Bios settings and looked at "PSU Idle Control" setting and it was reset to 'Auto'. I set it back to "Typical Current Idle" and everything has been working fine so far. This is huge because this will prove it to be this setting with the usb ports disconnecting on my system any how. I will continue to monitor. Hope this helps others out.

Update: April 14th. Still running strong after setting the PSU Idle Control to Typical Current. I have played games and letting it idle for days. Not one USB disconnect or freeze during use and idle.

Just to give an update:
I don't know why, but after using timeshift to roll back to a few hours old backup (because of an unrelated issue), it seems to work. My leading theory currently is that something somewhere had been corrupted by the previous SSD which had failed, and got fixed by Timeshift.
