But now here it is: I replaced Logitech M-BJ58 with M100, and. Ruslan (in 2019) comments 'I've also used lots of USB mice, and until now I hadn't come across one without support for PS/2 via an adaptor. I just use mouse/keyboard like a normal joe and don't know about dpi in regard to mice. The mouse is cheap and finding out if it works is like less than a minute once you get the items i'd just buy it and try it. Though I suppose it's possible maybe there are some that don't and you could get unlucky, but I doubt it! I have tried many USB mice/keyboard, cheap ones, and without me having to check, and they've all supported them. I had also heard that all USB mice/keyboard seem to support Ps2. The issue is the other way, Ps2 to USB, then you need a big adaptor with special circuitry.īy the way, when I tried USB-Ps2 adaptors, some slightly larger green ones that looked like the ones you pictured, were a bit picky, but some slightly smaller ones that happened to be red and purple seemed more reliable in that they seemed to work in all my computers including a picky one(they were from a convenient rip off elecronics store called maplin). The USB mouse/keyboard always supported PS2. I had a bunch of little adaptors, different makes. (apart from situations where the little adaptor was picky and the computer's usb port was picky.

I have used loads of USB mice and keyboards and those little adaptors always work with them.
