i tested the patch with rates of 1, 100 and 1000: 1: random copy&pastes when moving the mouse 100: also random copy&pastes when moving the mouse 1000: OK setting hw.usb.ums.debug=15 indicates that the polling rate is set exactly to moused's -F value. at some point i experienced a crash including a reboot. no core dump was produced however. i've tried to reproduce the crash but wasn't able to. i think the crash occured when i booted with a low -F value, then set -F to a higher value in /etc/rc.conf and after that unplugged the mouse and plugged it in again. as i said i'm not able to produce the panic any longer. might have been caused by old code fragments in my /usr/src. alex Hans Petter Selasky schrieb am 2009-07-14: > Hi, > On Tuesday 14 July 2009 13:28:28 Alexander Best wrote: > > thx for the patch. i'm recompiling my kernel right now and will > > test the > > changes right away. any reason you limited the rate to <= 1000? i > > had a > > quick look at the specs of my mouse: > USB has a limitation of polling 1000 times per second. > > - 6400 frames per second (5.8 megapixels per second) > > - 1800dpi Razer Precision 3G infrared sensor > > what about the mouse resolution? moused comes has the "-r" switch > > to change > > it. would usb mice benefit from that option? > I'm not sure if setting the mouse resolution has a standard USB > request yet. > Else it would not be much trouble adding support for that aswell. > --HPS
