Powertop prints: 11.5 W 100,0% Device USB device: USB2.0-CRW (Generic) This problem was not there when inspecting the power usage a few weeks before. Also when inserting actually a sd-card the power usage shrinks drastically so it is not even seen in powertop on the first places. I have tested it with kernel version 5.13.0-21-generic and 5.13.0-22-generic and the problem exists on both, but it seems a bit worse on 5.13.0-22-generic. I have not configured anything manually there. lsusb prints for the sd-card reader the following: Bus 001 Device 003: ID 0bda:0138 Realtek Semiconductor Corp. RTS5138 Card Reader Controller I am using Ubuntu 21.10 Summary: Ubuntu 21.10 Kernel version: 5.13.0-21-generic and 5.13.0-22-generic tested What I expected to happen: SD card reader *not* eating up all that power when not even in use What happened instead: SD card reader eating up all that power when not even in use To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1953557/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
