Title:
  sd card reader runs 100% of time and consumes way too much power

Status in linux package in Ubuntu:
  New

Bug description:
  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
