After the last `dnf update` and system restart, I keep hearing the sound effect for (un)plugging of a USB drive from time to time. I don't see any other symptoms but I do see a bunch of these on the kernel log:
```
[ 4873.577447] usb 1-4: reset full-speed USB device number 2 using xhci_hcd
```
ls-usb doesn't help identify what device is that:
```
/: Bus 001.Port 001: Dev 001, Class=root_hub, Driver=xhci_hcd/5p, 480M
|__ Port 004: Dev 002, If 0, Class=Vendor Specific Class, Driver=[none], 12M
```
Anyone know? It's driving me crazy. I have work to do..
Ironically I updated+rebooted in hopes that the horrible issue I've been facing for a month now where strange artifacts appear on my screen and text in Chrome and Slack just become garbled, will finally would have been fixed. But no! Now I have one more annoying issue.
I guess upgrading to Fedora 41 was a mistake. Maybe I should downgrade somehow?
Oh, it's a known issue: https://community.frame.work/t/screen-is-glitchy-with-colored-pixels-moving-on-fedora-41-laptop-13-amd-ryzen-7040/66117/25
Apparently downgrading Mesa helps so I'll try that. Hopefully it helps.
@zeenix there's probably a bug inside unplugging the USB controller…
@zeenix same here on Alpine, so must be some upstream linux or utils bug?
@zeenix I've also started hearing that after a recent update on EndeavourOS (arch-based).I assumed one of my peripherals was bugging out, but it sounds like it may be software.
@zeenix That's why I really like Silverblue. You don't even have to downgrade and can just boot the older version by choosing it in Grub.
@gdesmott right, I tried it some years ago but couldn't get some essentials working so got frustrated and switched away.
Maybe I'll give it another go in a few months time (right now i need a working machine so I can't afford to experiment).
