Hi, I just subscribed to the linux-usb list as an occasional user ... I glanced through this thread backwards ... and am somehow surprised nobody objects. I am no expert but it is my impression a lot of us want CPU powersaving, maybe LCD powersaving and don't care about external USB devices. It is only causing a hassle if the mouse goes sleep every 2 seconds or first keyboard keystroke goes away because it just woke up the keyboard. Even worse if a usb-storage device goes sleep and kernel chokes on subsequent file access. Sure, it is because of broken devices, firmware, sometimes linux ... but why do I have to sacrifice all power-saving to avoid potential issues. I just do not want to hit new bugs here or there in powersaving features in USB devices, really. They are cheap, crappy and I accepted it. But please, don't make me either use their power-saving or disable powersaving altogether. I believe you know very well what in kernel is affected and if you say few lines of code are affected, but do you really want laptop-mode-tools and all other to change their documentation, config files and make all the whitelists and blacklists in their config files useless? If I get it right I either use the tool as a whole or not at all? Really? I must be missing something. sorry for my incompetence taht I am not so knowledgeable of power-saving in general. Am just a 'looser'. ;) Martin Greg KH wrote: > On Tue, Dec 18, 2012 at 11:11:15AM -0500, Alan Stern wrote: >> I suggest that we remove the CONFIG_USB_SUSPEND option, starting in >> 3.9.
