Razer Abyssus and Ps/2

Hey guys,

I recently bought a Razer Abyssus. It does not include a USB to PS/2 converter so I used the one I got from my Logitech keyboard/mouse set. The problem here is that the mouse doesn't work. Is this a known problem or is there something wrong with my mouse or computer or converter?

Thanks.

I don't think the controller supports the device working on ps/2 ports. I'm not sure though.

Probably this, I don't see why you would use a PS/2 port over a normal USB

Keyboards work better on PS/2 ports, but mice don't.
There's no point in using a high performance mouse (high polling, macros, stuff) with PS/2 as lots of features aren't supported.

There's your answer.
Many usb mice are not compatible with PS2 adapters. Not even the Microsoft intellimouse series which is quite old.
Some USB keyboards however will benefit from using over PS2, such as my 6gv2 which has no ghosting when hooked up with PS/2 adapter, meaning that if I press every key, they all register. On usb I think it has a limit of 6 simultaneous keys. Not that it really matters =P

Plus, PS/2 doesn't have to be reported every x miliseconds (doesn't have a polling rate like the USB port), it's sends the signal right away on actuation.
The lag for keyboards is less on PS/2 because a key press doesn't have to wait to be reported in the next poll and therefore uses less resources as the cpu only works on key actuation, however the datapath for mice is inconvenient due to the higher amount of information it reports when moving and because mice have more advanced features that require the wider USB datapath like specific hardware recognition, saving macros, profiles, changing cpi, etc.
That's why some brands insist on using usb on keyboard so they can add those profile gimmicks and stuff you probably won't need, despite the fact that PS/2 is superior for that kind of hardware.

The USB 1.1 > PS/2 adapters were actually provided with any retail or OEM purchase. They "work" as any other PS/2 tracking device under windows.

PS/2 controllers had the same type of datapath limitations as USB spec'd mice of the time. The move to USB was simply due to general standards of peripheral hardware.

PS: PS/2 mice defaulted @ 10ms or (100hz) regardless. A max of 200hz was or is possible is registry modification.

In terms of the Abyssus, I don't believe spec 2.0 controller supports that feature. Not sure if they made 2.0 converters and if it will work with that specific mouse.

I also don't see the point of PS/2 on keyboards, but that's another story.

there might be some truth to what zareliman says. When i plug in my keyboard via PS/2 adapter, BHOP away, when i plug it in regulary via USB, BHOP no more.
