#6727: Asus A7N8X-X: USB mouse CPU drain... ------------------------+------------------------- Reporter: Luposian | Owner: nobody Type: bug | Status: new Priority: normal | Milestone: R1 Component: - General | Version: R1/alpha2 Resolution: | Keywords: Blocked By: | Has a Patch: 0 Platform: x86 | Blocking: ------------------------+------------------------- Comment (by Luposian): Ok, I finally got around to testing out a different USB mouse. It's a USB Kensington ball mouse. When I plugged it in, after unplugging the Logitech Trackman Marble, I was shocked to see I went from using 25% CPU (Pulse shows 20 "bars", so 5 bars (which were lit green) = 25%), to less than 1% (Pulse showed nothing, but the little CPU indicator at the leaf menu/task bar was blipping a single little purple line). But that wasn't what shocked me most. No, the BIG surprise came when I unplugged the Kensington and plugged the Logitech back in... it was showing the SAME amount of CPU usage... which was next to nothing! So, as I understand it, this is simply a USB initialization thing... if you unplug the USB mouse/trackball and plug it back in, the CPU usage issue goes away! I will reboot and test this theory (with just the Logitech). -- Ticket URL: <http://dev.haiku-os.org/ticket/6727#comment:6> Haiku <http://dev.haiku-os.org> Haiku - the operating system.
