hi there, i've reported this issue quite a while ago [1], but back then nobody was able to help me. i have an issue with my usb mouse. when there's a high CPU load it produces random mouse clicks. this doesn't happen on other OSes. i've attached a different usb mouse to my freebsd box and i could't observe the same behavior. so it seems this problem is only related to specific mice. back then hps@ guessed that my mouse requires a certain polling rate from the host. during high cpu load the host couldn't keep up the polling rate and thus the mouse starts producing wrong output. i've uploaded i video [2], so you can oberserve what happens exactly. please note that during the whole video i didn't touch a single button, but only moved my mouse along the x and y axis. cheers. alex [1] http://www.mail-archive.com/freebsd-usb@freebsd.org/msg05766.html [2] http://vimeo.com/19037272 -- a13x
