I got an Asus X200M laptop back around May and I have been running arch on it since the start. One problem that has cropped up in the past few months has been that every once in a while, the touchscreen or trackpad (or both) will stop sending input to X after the computer resumes from a suspend. Until this week, I had simply restarted the machine to fix the problem (a solution I despised).
The thing that changed this past week is that I suddenly was unable to use a Logitech USB mouse after plugging it in. My movements of the mouse had no effect. I googled around and found out about the xinput command and using it I discovered that for some reason the mouse was a "floating slave" and wasn't attached to the virtual pointer which caused it to appear to not work. At that point I used the xinput command to manually attach it and all was well. Then, the next time my mice stopped working after a resume I ran the xinput command and got the following:
[508]kcuzner@kcuzner-netbook:~$ xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ Asus WMI hotkeys id=12 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
∼ USBest Technology SiS HID Touch Controller id=10 [floating slave]
∼ Logitech Unifying Device. Wireless PID:1025 id=11 [floating slave]
∼ ETPS/2 Elantech Touchpad id=14 [floating slave]I was extremely surprised! Something had made all of my mice become floating slaves! I looked at my log and discovered the following lines right after I resumed the machine:

Dec 26 20:46:30 kcuzner-netbook kernel: PM: Finishing wakeup.I don't know if these are the culprit of my issue, but it doesn't seem out of the question. Reattaching all of the pointers to the virtual core pointer fixed the problem of the mice not working.
My questions are these:
- What is causing my devices to become floating when I resume?
- How can I prevent this from occurring? It's extremely annoying.
I've attempted to search for this problem, but half the issue is that I don't know what to search. I end up getting results like the xinput manual and people trying to disable their mouses and such.
