Yep A Hitman is right USB 1,2,or 3 is more about the bandwidth ( read/write speed ) for file transfers, a mouse or keyboard uses so little resources that it will not matter if you used usb1 2 or3.

same.

max polling rate is determined by the peripheral.

 

a USB 1 port can do 1000hz; which is about the best a gaming mouse can do.

Really, any polling rate at, or over 250hz is more than enough for gaming.

 

I can tell the difference between 125hz and others; but once you're above, its all in your head. Get a mate to do a blind test if you don't believe me.

Thanks for opening a thread to answer your own question. :P

 

 

Looking forward to the next one.

From your wiki link:

"For USB1 low-speed (1.5 Mbit/s) and full-speed (12 Mbit/s) devices the shortest time for a transaction in one direction is 1 ms.[81] USB2 high-speed (480 Mbit/s) uses transactions within each micro frame (125 µs)[82] where using 1-byte interrupt packet results in a minimal response time of 940 ns. 4-byte interrupt packet results in 984 ns.[83]"

 

If you're coding for hardware at the firmware level, this is important information. For an end user, my point stands, there is no difference for your mouse between USB1 and 2.

 

If for some odball reason your mouse requires bi-directional transfer, USB 1 is still able 2ms response times. which is bullshit quick and faster than our brain, eyes, and certainly our muscles can even sense.
