Logitech G9x not recognized after resuming from hibernation

My favorite mouse, the Logitech MX518 needed to be badly retired after nearly 5 years of constant use.

After doing a lot of research and pouring over size comparisons I settled on  Logitech G9x Laser Mouse.  I really didn’t like the feel of it at first with the narrow precision grip but found a perfect fit with wide-load grip attached.  I’ve been using it for several weeks and feel like I’ve found the one.

Unfortunately I’ve been experiencing a perplexing problem lately.  I’ve got a fairly power hungry desktop and I like to put it to sleep/hibernation whenever it’s not in use to save a little on electricity consumption.  On resume however the G9x would sometimes not wake-up with the rest of the PC.  I could either:

  • Unplug and re-plug the USB cable
  • Use the keyboard to go to device manager and scan for hardware changes

Either of these would allow me to use the mouse.  I put up with this for a little while thinking it might just be a bit of a fluke on a new build, but after dealing with it for a while I concluded that when I resumed the PC from hibernation, 1 out 3 times the mouse would not wake up.

Fortunately, there is a quick and painless permanent fix.

My ASUS P9X79 Pro motherboard supports the USB Selective Suspend Setting.  This can be handy to save a little electricity for devices that pull power via USB.  For some reason, the G9x was being hung up by this setting.  As this particular power setting doesn’t really affect me (I don’t have a lot of USB powered devices attached) I disabled it and the mouse has been resuming normally ever since.

For those comfortable with navigating around Windows simply follow this path:

Control Panel → Hardware and Sound → Power Options → Change plan settings (for your plan) → Change advanced power settings → USB Settings → USB selective suspend setting → Disabled
