Still questioning 1000 Hz polling on mouse/keyboards. Unless the board has a dedicated gaming usb with 1000 Hz, its absolute useless. and most ppl i know that have one, usually buy in the +100$ range, so 80+% on the market wont really need it.

Yeah this simply isn't true; any usb 2.0 port can easily do 1000hz polling.

@Toss3 then why are there gaming/higher end boards with dedicated ports that offer 1000ms polling? where is this listed for usb (2.0) specs? then again, its late and im tired 😉 http://www.usb.org/developers/docs/usb20_docs/

Because marketing. Think about USB data packet size, and number of times per second this packet has to be transferred for USB 2.0 to reach its full bandwidth. Only possible difference with "dedicated" USB port is that it does add less latency than one on southbridge. IIRC Ryzen has few USB ports directly going to CPU.

makes sense, but then again i haven't seen anyone that says its a "fact" on ALL usb 2 (or 3) equipped boards. and i dont see anyone buying a +200$ board (vs a 100$ one) just because it has a dedicated (1000Hz) mouse port. they could actually make more money, by implementing/marketing it on mid range boards as well.. im not saying 2.0 cant do 1000Hz, but there is a difference between can and will, especially with all those different vendors for boards.
