My HDD devices connected to USB 3.0 when I'm already using the system does not get detected by lsblk and by udiskie. dmesg says:
usb usb3: root hub lost power or was reset
usb usb4: root hub lost power or was reset
If reboot or if I plug in the devices and then start the machine, then it gets detected and everything is fine.
USB 3.0 flash drives work as expected--problem is only with external HDD 3.0 drives. Sounds like some autosuspending/power-saving USB issue but I don't recall explciitly using any power-saving settings (I'm on a window manager so no potentially conflicting DE tools). My few udev rules have nothing to do with USB settings (maybe I tried one a while ago it is removed).
I have powertop only to monitor power usage (I don't think it automatically applies any power-saving settings) and have thermald installed (this controls temperature though, so I don't think it's relevant).
