http://askubuntu.com – I have a problem with card reader in my notebook with Ubuntu 12.10. It's usage is always at 100% and powertop shows it's power consumption as 16W or even more (which is really really way too much for a card reader). This is the line from the powertop: 16.7 W 100.0% USB device: USB2.0-CRW (Generic) How can I reduce wakeups or disable this card reader? (I don't use the card reader very much) (HowTos)
