Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Serial vs. USB 2.0 for mouse
- Thread starter Glow
- Start date
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.
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.
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)Originally posted by Iconz1
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
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.

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.
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.
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.
