Once it gets one, it knows without a doubt what it is connected to. I found some pictures from 1999 Comdex stage with Bill showing off huge Intellimouse Explorer model Cant locate any video from that keynote, maybe Microsoft enforced no filming rule after their 1998 Comdex BSOD live on stage performance:) I even have one of the original Intellimouse Explorers, sadly unusable, 17 year old scroll wheel rubber is seeping elastomer? And melting:( Interview with Gary Gordon, the HP/Agilent(now Avago, best mice sensors available) inventor, mouse bit at 29:40: spoiler, he didnt get shit for his inventions, he elaborates at 40:10. I thought I was a hoarder. I have long since disposed of all those mouse adapter dongles. I do however still have one of the very first Microsoft Optical Wheel mice (pre-Intellimouse) from 1991 and it still works perfectly.

Such devices are generally equipped with a USB connector and ship with a wiring adapter to allow connection to a PS/2 port. Such passive adapters are not standardized and may therefore be specific to the device they came with.

(typical examples of passive ps/2 to USB adapters that are not true ps/2 to USB signal converters) Answer: The vast majority of commonly available ps2 to USB converters are simple passive ADAPTERS that simply change the plug shape to match the outlet. These ADAPTERS only function to connect the ps/2 wires to the approximate USB wires. Simple ps/2 to USB adapters do not use specific software drivers. In general, most users having trouble connecting their keyboard to newer computers are looking for a ps/2 to USB signal CONVERTER. These devices use an integrated circuit (pre-programmed chip) to actively translate the ps/2 keyboard signal and convert it into a USB keyboard signal.

Though he's not actually a real singer per say, it doesn't change the fact that he's a incredible song writer and when he does sing, it works for the songs he writes. And Of course you have records like “Motto” on which Drake completely channels the Bay Area, already becoming a street anthem, though I feel like Lil Wayne under delivered on his feature. Speaking of features the album has the right amount and didn't go over the top, that Kendrick Lamar interlude was definitely a good look and is surely a prelude to something else to come from Drake and Kendrick. Take care drake tracklist. Then you have the best-of-both-worlds joints like “Shot For Me,” “,” that have a great balance of both versions of Drake and of course the title track “Take Care” featuring Rihanna, which I guarantee you will be the biggest record on the album. Songs like “Doing It Wrong,” “The Real Her,” and “Good Ones Go Interlude” are all solid R&B stacks that any R&B artist will respect.

The PS/2 port can be clocked up to 200Hz for silky smooth sampling. OK, using third party software you can do that but by default the sampling rate of a USB mouse is 125 and a PS/2 port is something like 40. But I just read here that cpu usage is higher for USB mouse compared to PS/2 so if you want to save cpu cycles maybe PS/2 is better.

The interface has two main signal lines, Data and Clock. These are single-ended (common mode) signals driven by open-collector drivers at each end. Normally, the transmission is from the device to the computer; then, the attached peripheral device generates the Clock signal. To transmit a byte, the device simply outputs a serial frame of data (including 8 bits of data and a parity bit) on the Data line serially as it toggles the Clock line once for each bit. The host controls the direction of communication using the Clock line; when the host pulls it low, communication from the attached device is inhibited.

I read that here.

USB mice by default have a better refresh rate usually above 100Hz and up to 200Hz so may be a bit smoother and don't require a specific IRQ although this is less of an issue these days with the advent of APIC on the newer O/S.

It must be a cheap and simple thing to do. I am teh 3733t hX0R. If you are a master electronics technician with degrees in EE, you could of course take the time and money to do it yourself.

Wonderware intouch versions. If the tag is not active in InTouch or if the value does not change in the serial device, the server will not advise InTouch of the point’s value. Once initialized, the I/O server will check for the point to change in the serial device and will advise InTouch when its value changes.

• Keyboard and mouse ports may be combined into a single port which can be used to connect both by splitter cable. • Sometimes, keyboard Data for splitter cable. • Sometimes, keyboard Clock for splitter cable.

Normally, for a basic mouse, I prefer to use the ps/2 port, because that port has no other function, and I don't like to waste it.

The PS/2 port can be clocked up to 200Hz for silky smooth sampling. OK, using third party software you can do that but by default the sampling rate of a USB mouse is 125 and a PS/2 port is something like 40. But I just read here that cpu usage is higher for USB mouse compared to PS/2 so if you want to save cpu cycles maybe PS/2 is better. I read that here.

For a bit more of a complete answer - a lot of modern mice and keyboards have processors that can handle both the PS/2 and USB protocols. In these cases a passive adaptor that simply changes the physical connection will do. There's two scenarios where you need an active connector - firstly, where power draw is significantly higher than expected - some old Model Ms fall under this category. The second is where the mouse is old enough that it dosen't actually speak USB. Interestingly the famous blue cube I recommend when people are looking for such an adaptor may not work for mice - you'll want an active converter with a mouse specific port - which often means a USB -> 2x PS/2 converter.

(I prefer the older keyboards that have a better feel to the keys.) I connected my old keyboard and mouse (PS/2) to this adapter/converter, and my Windows 10 recognized the keyboard and mouse immediately upon booting up. I have not discovered any issues, and my keyboard and mouse appear to have full functionality. (Note: My new PC and my old keyboard and mouse are from the same manufacturer. I can't comment on the outcome if the manufacturer of the PC is different from the manufacturer of the keyboard and mouse.) PROS: Functions as I had hoped. CONS: None Write your review here. It must be at least 50 characters long. Consider whether you would recommend this product and what you like or dislike about it.

The issue isn't this converter, rather it is Windows not supporting USB 3.0, until Windows is fully installed. I have successfully used this in many USB 2.0 ports. • • • on Dec 19, 2016 • Purchased on Sep 1, 2016. I didn't like the wireless keyboard and mouse that came with a new desktop PC that I recently purchased running Windows 10.

Such adapters only support certain classes of USB devices such as keyboards and mice, but are not model- or vendor-specific. Older PS/2-only peripherals can be connected to a USB port via an active adapter, which generally provides a pair of PS/2 ports at the cost of one USB port. Color code [ ] Original PS/2 connectors were black or had the same color as the connecting cable (mainly white). Later the standard introduced a color code: the keyboard port, and the plugs on compliant keyboards, were purple; mouse ports and plugs were green. (Some vendors initially used a different color code; used the color orange for the keyboard connector for a short period, but soon switched to purple.) Today this code is still used on most PCs.

This part does not actually plug into any PCI slots of the motherboard, but insteads uses a 24-pin ribbon cable to connect directly to a special connector on certain Dell Optiplex motherboards. The keyboard interface is an elementary low-level device and it needs to be initalized very early during the boot process. Any true PC hardware geek with real-world experience knows that the PCI bus is not setup and cannot be used to capture the type of direct, low-level I/O signals between the keyboard and computer. Question: Why is it so hard to find an USB adapter that will make a vintage IBM keyboard interface with a modern Intel motherboard. Answer: Online reports indicate that vintage IBM ps/2 keyboards pull up to 25x-40x more current compared to modern keyboards. See references: (, ). One way to resolve this problem to add resistors to change the voltage, or an easier non-destructive fix is to use an active ps/2 to USB plug-in converter with built-in electronics.

I have lots of experience of them not working. On a related note, USB devices have inbuilt support for ps2 and a little adaptor thing like you pictured but the other way, will let you plug a usb keyb/mouse in a ps2 port. But if going ps2 to usb, with a ps2 device, then no, you need a big style adaptor. They look different. Every ps2 keyb i've tried has not worked with the little adaptor.
