I've already started to bulid my AMD K6-2 DOS/Win95 time machine PC (super-socket 7 board) last weekend and i'll show also some photos later in another post.
But i had also an incident/ problem which i wasn't able to solve, even after the install of different drivers and several re-install of windows.

The problem: my logitech optical usb mouse (M-UV69), connected with a usb-to-PS/2 adapter, will definitely not work using mouse PS/2 port on Win95 or Win98.
I've tried it with several drivers, logitech mouse ware 8.2, 9.6.1 on Win95 and also 9.7.9.1 on Win98.

Due to the situation that i've installed Win95b with USB support, i've installed additional driver for this USB support, but with direct USB connection the mouse don't work. With Win98 and USB, i can use it.

During installation the mainboard, i was staggerd to see a little damage directly at the boards corner near the two PS/2 ports. The bottom keyboard port works fine with a USB-to-PS/2 adapter, anytime. But the top will not.

I will also run Windows in MSDOS mode, so the mouse will not work with a dircect USB connetion i asume, or not?

The main idea now is to use an adapter PS/2 to serial port, cause the serial port will be definitely OK.

Actually i don't have a PS/2 mouse at home, only 3 with USB and one old one with a ball inside and serial port. So, i can't test it at once.

Yes, the adapter works. I've tested my keybord with the two adapters, without any issues. Edit: Works on my modern Core-I5 and at the bottom PS/2 port of my socket 7 board.

Many USB mice, especially more modern mice, omit the circuitry to use USB to PS/2 adapters.

Looks as if the mainboard was dropped at some point and landed on that corner of the PCB.

You're absolutely right. I've tested now the USB mouse with the adapter at the PS/2 port of my 'modern' Asus mainbord (P67-chipset). It doesn't work, so it's worse...
Anyway, the PS/2 port of the Socket 7 board might be OK, but i need a real PS/2 mouse.

The classic "took the impact from the fall into the dumpster corner".

The mothrboard looks fine though so if will probably work if you get a real PS/2 mouse.

Im not sure an USB adapter intended for a keyboard would work with a mouse, they often have different colours and thats probably for a reason. The only time you be sure a passiv USB to PS/2 adapter will work is if you got it with the mouse you want to use it with.
