I have a logitec USB/PS2 optical mouse, the el cheapo.
I had been using it with the ps2 adapter until I booted up and BIOS kicked about the keyboard. Taking out that connector enabled me to boot. So I plugged the mouse into the USB and it simply worked. Hats off. Next time I booted up, it did not work. Unplugging and replugging it and voile. Next time I booted up, it did not work and reconnecting also did not work. I get the disconnect notification notice identifying the mouse, etc. I do not get the connect notice like I did the last time. So . how do I get this to work reliably?
