Public bug reported:
My Canon CanoScan LiDE 220 scanner had worked reasonably well, until a
new kernel has been installed. It went into stop-and-go mode, and made
funny noises. This is worse in higher resolutions.
I had a notion that it might be a problem with USB, which in turn resides in the
kernel. I was right. The most current kernel, which has been installed, was
version
4.15.0-50. The previous one (which still is available via GRUB) was version
4.15.0-48.
I tried that version, and the problem went away.
I'm using Kubuntu 18.04.
