problem with USB mouse on A4000T

Wow - never saw that doodad before. Some incredible stuff coming out of Poland these days. But as to why it's not 100% compatible... not surprised. That USB to DB9 conversion is logic controlled, so unless you can update its firmware (which I highly doubt they designed it for that), you're going to be SOL buddy! That's a goofy piece of kit you have there. Kinda surprised it works at all. lol

I know there are utilities on Aminet that aid in using PC mice and such, but I'm sure they wouldn't work with your device. Might be worth searching though...

Logitech mouse just lit up but didnt work and the microsoft one didnt even light.

Ummm... the M$ mouse... douse that in some petrol and then ignite. She'll be lit but good after that! lol

Still no luck getting this adapter to work. So far tried 3 mice and only one worked.

I've heard Amiga mice work extremely well with Amiga computers and the upside is you don't need a $20 adapter either! lol

Okay, I'll stop now  

Did you try looking on Aminet for any drivers? Most are serial port drivers IIRC, but there might be something else of use. There's also a scrollwheel driver there too...
