PS/2 to USB Adapter...HOT!!

[bobbyw]

I ran into this on another forum and I thought I'd share it with you guys:

PS/2 to USB Adapter: $7.49

Incredible Hulk Window Decal Applique: $2.79


I wanted to use the PS/2 adapter on my KVM switch and luckily this one supports it!

pretty kewl device, but i've seen ps/2 to usb (mouse only) for like $3 bux. not sure how much it costs for those that come with 2 ps/2 ports.

I always wondered why these kinds of adapters were so expensive. I mean there have been offers in the past where you get PAYED to take a mouse/keyboard yet on these silly devices they charge you 7 bucks for it Wouldn't it be better to just get a new one altogether?

Do not use USB mouse without a PS/2 adaptor and avoid USB keyboards.

They do not work in DOS, BIOS.

USB signals can be processor intensive so the system will run faster if PS/2 port is used.

It seems that sometimes you need to for functionality. Like my old Intellimouse Explorer. The Back/Forward buttons dont work when it's plugged in by PS/2, but once I plug it in USB, then it works fine. Is it just me?

It's just you :beer:

I have a USB mouse and a USB to PS/2 adapter and for some reason I can't use that mouse on a KVM switch. Anyone else have this problem?

They do work in DOS/BIOS if your bios supports legacy usb.

As for processor intensive. if you think so. I guess they're as processor intensive as a 56k winmodem is in a 2ghz system.
I'm sure that 50mhz you're using for the winmodem is going to waste.

i thought it was for Playstation, i need another one of those or better i actually need those N64 to usb adapters, wonder if there are any good deals on those

The refresh rate on USB is also around 10x that of PS/2 which (arguably) could make a difference when playing games or other tasks where precision controls are needed with the house.

The standard refresh rate for ps/2 is 40hz. USB is 120 hz. However, in recent microsoft oses it automatically overclocks the ps/2 port so there is little discernable difference.

I thought it was 10 hz vs around 100hz, but you very well may be correct.

 

[CheetahMk2]

I dunno.. I could only see this being useful on a laptop without a Ps/2 splitter, or an old AT keyboard-only system which somehow had a USB port. And about not being able to use USB k/b in DOS, I do it all the time. There is an option in all BIOS'es nowadaysto support USB keyboard, and mouse.

USB is 125hz, Ps/2 can be clocked up to 200hz, however. (although windows 2000 doesn't allow this, only up to 100hz, after that it makes weird problems in gaming in quake3 etc... for some strange reason -- somethign about input buffers if I remember, don't take my word for it though -- but I do believe it works in windows xp up to 200hz, I forget )

ps/2 rate changer proggy for windows 98/95 (anyone still use those?? heh), or the mouse properties dialog in device manager has it in windows 2000/xp or your mouse properties dialog in the control panel depending on your mouse.

No real discernable difference between 125hz/100hz, I notice a bit between 120->200hz, however, I can't do that because of windows 2000

<sigh>

Here's a mouse rate checker: here if you're interested in what you're running at

Going from windows 98 -> windows 2000 I think that's the only downside I've found so far--my mouse rate (in gaming it's a bit smoother feeling)

If anyone knows how to change the refresh rate on the ps/2 port up to 200hz in windows 2000 without noticable problems, I'll uhm, give them gifts

 

[RDMustang1]

Limit one per purchase (more can be purchased at $14.99 each)..

Cool item.. don't need any but I could see needing some down the line

 

[slothman]

Just as an interesting sidenote, there are usb drivers for dos that allow mouse/keyboard/cdrom/other functionality. Good for ppl who have bios's that suck too hard.

 

[0roo0roo]

i've read that usb is less stressful on the system in the end then an overlclcocked ps2 which really is an ancient tech. probably evens out in the end.

I picked one of these up (different brand) at the marketproshows here in Memphis last weekend for my IoGear KVM and it works great. These seem to work well with KVMs

 

[huesmann]

I have a dozen PS/2 to USB adapters lying around from the USB mice they came with.

I believe you are mistaken, this adapter plugs PS2 type keyboards/mice into a USB port.

You are thinking of a USB to PS2 adapter commonly included with USB based mice not a PS2 to USB adapter listed here.

Yeah all right let's see:

1. Downloaded that Mouse rate checker.

2. Windows Me, Logitech MX700 Cordless Optical Mouse with regular Logitech drivers.

3. Around 120 Hz that's with PS/2 adaptor.

4. Going to unplug it now at plug it in with USB directly without PS/2 adaptor:
Around 120 Hz with USB only.

So, there goes that. If anyone could post one reason not to use PS/2 adaptor, please do.
Still standing reason to avoid USB without a PS/2 adaptor: compatibility probs with older software.

 

[kami333]

Haven't had any issues with software at all.

Reason to go for USB: hotswapping. Not that I do it often but the times I do make up for it.

Geez . . . you think everyone is running on 2ghz systems?

Chieh

 

[c627627]

Yo, edit your post. You're quoting me for something I didn't say. It was the other guy.

I see you are correct. My bad.
