If I attach a USB adapter to my PS2 mouse, does the PS2 then become a USB device and can then be hot swapped? Or is it once a PS2, always a PS2?Try it and see. heh, thats how i learned most of what i know... trial and eroor, ive never used a ps2 to usb port, but, windows seems to regonize everything else thats plugged into one, which is quite annoying bc my mouse has to be re installed if i plug it into another port, and there is one port where it seems to have been DISABLED, although i cannot look, seeing as it will not regonize it... meh, i cant complain, the mouse was free, my school was THROWING it away, saying that it DIDNT work... somone probably just disabled the driver, lmao... but i get home, plug it in, windows regonizes it and i have a "dell" optical mouse, for free... got the keyboard from the school aswell, some kid switched around the keys, and i saw it sittin in a PILE of boxes, with two other OLD dell "quiet key" keyboards, the librarian says i can have them, so i walk out of the building with a readers digest box with three keyboards in it, and no one, not even the reasource officer says a thing to me...
