Hello guys,
I am checking powertop to see and optimize details for battery usage and it is interesting to see a card reader which I don't use at all is draining the battery.
The battery reports a discharge rate of 9.48 W
The power consumed was 270 J
The estimated remaining time is 2 hours, 23 minutes
Summary: 1164.0 wakeups/second, 50.9 GPU ops/seconds, 0.0 VFS ops/sec and 18.0% CPU use
Power est. Usage Events/s Category Description
6.45 W 82.6% Device USB device: USB2.0-CRW (Generic)
996 mW 51.9% Device Display backlight
lsusb reports the device

How can I completely power it off permanently?

That is an estimate and if following the usb spec to the letter it should not even be possible for a usb2 port. I suppose powertop might have/suggest some tunable that might make the card reader sleep when not in use.
