Dear Sirs! When I move the mouse too fast / not slow enough, I get the following in dmesg, many times:
wsmouse0 detached ums0 detached uhidev0 detached uhidev0 at uhub4 port 2 configuration 1 interface 0 "MOON AND" rev 1.00/0.10 addr 2 uhidev0: iclass 3/1 ums0 at uhidev0: 3 buttons, Z dir wsmouse0 at ums0 mux 0 << This affects negatively the responsiveness of the mouse. It may also happen, that the mouse is not recognized again. I observed this behaviour with OpenBSD 4.8 and OpenBSD 5.8 in different machines, as also with FreeBSD. I have little experience with USB mouses and use till today a PS/2 mouse: the wheel is with PS/2 very responsive independent of the speed. Is this normal? Is it a problem of the mouse? Is it the (automatic) configuration of X11? Can I do something against it? Thanks Rodrigo.
