Hmmm.. I have the cheapie mouse that came with an IBM computer that has 
a terrible time with it's optical sensor. Every once in a while the 
cursor will jump a far distance from where I was for no good reason. 
Never has happened on the various MS opticals I've used, but this one 
does it repeatedly.

maybe this has something to do with it

lol, yeah that happened to me too: at my work I'm using a USB mouse that 
  didn't even move when connected to the USB port but with a USB --> PS2 
adapter the things is alive and kicking. Looks like the USB interface of 
the mouse is not working well enough for the USB port but enough to 
"hand shake" with the PS2 interface. I really would like to know why 
this happens.

I loved your: "So far it was worked utterly flawlessly ever since. Go 
figure!" heheheh :D

If the adaptor is simple, there's virtually no electronics in it, and 
what you really have is a mouse that will do either, with the signals 
going over different pins.

Check your BIOS for "legacy USB support" - that means to recognise mouse 
and keyboard on USB ports.  That's all I can think of offhand.

hmm, I think may have very simple electronics since both are serial 
ports and would explain why the flawlessness of the buggy USB mouse 
interface. At least is what I think.

Already did Darren, i'm a PC tech so was the first thing to check :)

You never read the USB spec, did you? It's actually rather complex. :-) 
That it's serial is like saying "SATA is serial" or "SONET is serial."

Cool. Heck, *I* didn't know what it meant six months ago. :-)

aren't they? maybe complexfor the very high speeds but AFAK they are 
serial techs, similar to PCI-Express.

I don't know about PCI-Express, but I'm just saying the fact that 
they're serial doesn't make them "simple". The USB spec is something 
like 250 pages or so, and that's just for the basics shared by all USB 
devices, like the ability to plug in, be recognised, and sync with the host.

(SONET is what telcos use to put voice and data over fiber, multiplexed. 
It's not simple either. :)

USB has a whole communications protocol to go with it. Think about 
TCP/IP and how complicated that is, and you get some idea of how much 
work a typical USB device has to do in order to work. Sure, the 
*physical* signalling is a simple serial bus, but if you want to *do* 
anything with it... ;-)

And also think of the hundreds of protocols you can talk over TCP.
