Comment 2 for bug 1834641

I did change the USB cables already, and also the ports, even the devices (Voyage). I'm not sure what else it could be at this point. I'm using Arch Linux up-to-date with KDE Plasma (if a DE-specific mounting mechanism is somehow relevant, although I think it's just UDisk, really). The Kindle (Kindle Oasis 2) is updated to the latest firmware as well.
