When inspecting the systems power usage trough powertop I recognized the sd card reader is running 100% of time and consuming between 8 and 16 W on my laptop despite not being even in use. 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
