Serial vs. USB 2.0 for mouse

Are serial mouses even made anymore? I haven't seen a new one in years. Likewise, I've never seen a usb2 mouse. Usb2 is completely unnecessary for mouses. They use such little bandwidth that ps/2 or usb would suffice. As far as ps/2 or usb, there's really no difference. I use usb because I can plug it into my keyboard and only have one cable going to my computer.
 
I think serial is slower, ps2 is faster, and usb is faster yet. (i think ps2 maxs at 700 dpi)

Im sure someone somewhere still makes serial mice, but mobos have been coming with ps2 for a long time.
 
would a a mouse plugged into a usb 2.0 port work up to speed w/out SP1 installed?

Yes.
Okay cause with my drivers and shit it says usb 2.0 support comes with SP1 and it doesn't instal so I didn't know if I would get the better performance with it over Ps/2

Why the heck does it say for some drivers u need to install SP1 to get usb 2.0?
 
If there's a PS/2 port, I just use that (With adaptor). There's no reason to waste a USB port if you can use a legacy port for the mouse.
 
Mice do not use USB 2.0, even if you plug them into a USB 2.0 port. And even if they did it would provide no benefit.

Windows XP was released before USB 2.0 was finalized. Thus it does not have native USB 2.0 support. SP1 adds USB 2.0 support.
 
Oh okay I thought new mice were basically designed for usb 2.0 I do a lot of heavy gaming and just got a logitech MX510 PS/2 can only see 700dpi someone said so usb 1.1 can see how much? and can it take advanage of the 5.8 Megapixels?

thats crap, i notice HUGE difference between serial and USB mice, optical or ball

belkin USB ball mouse, microsoft intellimouse (USB and PS/2, no difference for me), MX700, mx900, random no name serial mice

Differences like what?

serial is slow as hell, as in it has a very noticable lack of mouse location refreshes.

in any case, serial and USB mice arent even in the same BALLPARK, why is it an issue? if you want a crappy old mouse, you use a serial mouse. if you want something made within the past 5 years that will be at the very least workable, use USB. you cant get one or the other for any good mouse.
 
oh woops. i thought it said ps2 to usb.

sorry :( that's what i meant on the difference is unnoticeable

Dunno. But I've ran into that problem a few times. Just do what the man says and bend ov ...err install.

well then I agree with you :)

Okay bottom line for performance mouse PS/2 or usb?


i havent noticed a difference and you probabily wont. id use USB just so i could hot swap without problems, you can kind of do that with PS/2 but you really shouldnt.
 
USB should do it, unless you have some high-bandwidth usb device hooked up, like some sort of audio or video device, in which case you might be better off using ps/2.
 
The reason I like USB vs. PS/2 is that USB is "hot-swappable" and I don't get any annoying back-talk from my PC if I unplug it.

Besides, I really see an improvement with my 480mbps transfer rate on 2.0:rolleyes: :p

I'm still confused can I still get a high transfer rate w/out SP1 installed for my usb 2.0 devices or my soon to be (MX510)
 
You need SP1 to be able to use USB2. You can still use USB2 devices and USB2 ports without SP1, so long as those devices are backwards compatible with USB. You will not get USB2 speeds without SP1. As has been stated, USB2 wasn't finalized when windows xp was release, so it doesn't have support of it. SP1 has many other fixes and such so you might as well go ahead and install it.

Mouses don't really have a transfer rate in the sense that a network interface or a drive bus has a transfer rate. The sensors in a mouse cannot be polled fast enough to even come close to saturating USB. It would just be a waste of bandwidth.

That was a great description. So even todays mice don't even touch usb 2.0 speed?

Exactly, BTW, I was kidding when I said I get better perf. w/ 2.0 for that exact reason.;)

serial -> usb, yes. PS2 -> usb, no.

Ucky USB and Hefty Hertz
So what hertz? Well, in this case, it's how many times your mouse is sending and checking the mouse's position on the screen. So, lets say you have a PS2 mouse and your hertz are coming in at 97 on an average. Let's assume for a second you have a top of the line card and are pulling out 150+ frames per second in your game. That means your video is drawing your screen more times than your mouse is refreshing its position. This is bad. You want your mouse to be at least as many FPS you are getting in your game. The higher the mouse hertz, the better. This is where the fluid mouse movement comes in. Let's first look at the hertz of the mice we are comparing today:

PS2 Adapter on USB Mouse: 97 Hz Average
Regular USB for both mice: 124 Hz Average
PS2 Adapter with Speedup: 195 Hz Average

Regular USB
This is both mice plugged into the USB connection. No hardware or software intervention between the mouse and the USB port. As you can see above, it scores fairly decent at 124 hertz. So, as long as your frames per second in your game aren't going above 124 fps on average in your game, you will continue to experience a smooth fluid type motion.

PS2 Adapter with Speedup
After enabling a speedup in Logitech's MouseWare drivers, the USB mouse with the PS2 adapter scored a whopping 195 hertz on average. This is the best score you can get. It peeked at 238 hertz, but for the average 195 was as high as it went. Gamers should take note that a PS2 mouse with a speedup utility will enable it to have more fluid movement than a USB mouse. As of the time of this review, we were unable to find any type of USB speed up utility that would increase the hertz of a USB mouse. Using a speedup program with the PS2 adapter is key if you are looking for the most fluid movement that a mouse can offer.

Just a little information for those that care :).
 
That guy really has no idea what he is talking about. Hertz is a measure of frequency. Hertz don't "come in". Maybe what he is thinking of is the sampling rate. Nearly all mouses(yes, even ball mouses) use optical sensors which are polled to detect a change, which causes movement of the cursor. That whole webpage just sounds so ignorant and childish. I'm not even going to get into the whole frame rate vs. refresh rate thing. The only difference you can tell between a mouse at 100Hz and a mouse at 150Hz is all in your head. There's just no way you can move the mouse that fast for it to make a difference.
 
Wow I am so confused now. So my mouse with usb and it's Ps/2 attachment on with a speedup utilliy will be better than just it's normal usb?

Try it. If you can't notice any difference(which you probably won't) then it doesn't matter. I think a lot of these people who say to raise whatever are either just concerned with the numbers or they had it set really low to begin with. Try it and see which you like best.
 
where would I find a new version of this utility? seems funny to me that usb with a ps/2 attachement would be faster?

No, in fact, he is talking about the rate the system polls the PS/2 or USB port the mouse is on. The hertz is the rate of 'refreshes' the port is going under. The sample rate of a mouse is completely internal. It doesn't matter if you have the best sample rate in the world if your polling rate for the port is low.

But can a person really tell the difference between 100Hz and 150Hz? Regardless of what he is talking about, he still sounds childish and uneducated.
