For an USB mouse to work with those ubiquitous little green adapters, it has to support both USB and PS/2 protocols. What model is your mouse?

It's called Microsoft Optical Mouse 200.
I figured that something like that happened. 🙁

According to the data sheet (available here) this mouse only works on USB ports. I'm afraid you'll have to look for a model which specifically supports operation on PS/2 ports.

Hmm that's a good topic!

I think we could really do with a list of USB mice, that are compatible on PS/2 ports!

Found this mouse from Lenovo:

Attaches to PS/2 port via USB-to-PS/2 Connector Cable

And this is a really really good gaming mouse from MS Also states PS/2:

Microsoft IntelliMouse Explorer 3.0

We could add to that list any USB mouse that is sold with a PS/2 adapter included in the package.

Though frankly, it seems easier to just go get a PS/2 mouse (though they are getting a bit less common).

Yea, I got this Samsung PS/2 mouse and it's not very good.

It also cost more. Likely because it's now a niche product.

Wow....all these years and have never known that a USB mouse couldn't work with the adapter. Learn something new every day.

I thought Cutemouse could scan USB ports?

It's kinda the same for PS/2 mice when using a Serial adapter. If the mouse doesn't support the serial protocol internally, the adapter will not work.

It will but only if it is recognised in DOS. By default DOS has no idea of what USB is 😁

From CuteMouse's homepage:

'Modern BIOSes often make USB mice visible through the PS/2 interface if you enable "legacy" support in BIOS setup.'

I have a working UHCI driver for DOS, but it eats up > 100K of conventional memory so it's of no use to me...

I managed to get it working, it seems like I hadn't enabled the USB Legacy option in DOS 😖

I use a Logitech MX518 which works fine in DOS through a PS/2 adapter.

The logitech value optical mouse also works on a ps/2 port

it's build like a tank and it's cheap

2 years ago I bought a dozen of Logitech SBF69 mice from eBay:

these are ps2-only optical mice, no longer in production... I had one since when they where first announced and is working excellent after all those years... so I thought a dozen will last me a lifetime 🤣 🤣 🤣

I've got a small lot of these as well (may not be the exact same model though), these are excellent mice!!
Like em a lot!

Often these were rebranded as Dell, HP and Fujitsu also 😉

Edit:One problem some of these mice have, sometimes the mouse pointer teleports to some random location, but hey, I got them for around €2 each couple years back 😀

There are various versions of the Microsoft Optical/Intellimouse that are dual USB/PS2 compatible - I've got one here that states explicitly on the underside it supports both... the part number is X802652.

What I *would* like to find though, is another Logitech Trackman Wheel - the old white one with the red ball. Now that is a lovely thing... I have one on my main desktop, but I would love to have a second one on the KVM switch I run my SGI's, Amiga and retro PC through.

My last mouse (Logitech) was also working via a USB->PS2 adapter.

Now I have a PS2 only cheap Genius Netscroll one.

I am well aware PS2 ports are becoming a thing of the past for mainboards manufacturers. The trend is to add more USB ports. Thanks God newer bioses still have some rudimentary USB support for legacy Opertating Systems.
