For testing purposes, I stopped these systemd services:
1. systemctl stop smartmontools.service
2. systemctl stop udisks2.service
Last seen xhci-reset:
[Sat Mar 6 21:37:40 2021] SCSI ioctl error, cmd 85, prog pool-udisksd
So, that every 10min xhci-reset was caused by pool-udisksd from udisks2.service.
