Freezing mouse pointer - cause and solution

This had me going for ages, so I thought I'd share the solution with you.

System: newly built homebrew with Duo 6600 processor, 2G RAM and 7600GS
graphics, running Vista Home Premium. It's been running fine for the past
three months until a few days ago.

The symptoms were intermittent, brief "freezes" of the mouse pointer,
typically from a fraction of a second to perhaps two or three seconds. The
computer would fail to respond to double clicks during these freezes, as
well.

It may be that the whole computer was freezing for these brief periods, but
I didn't get chance to play any sound or video files to see if they were
stuttering.

Close monitoring of the processor loading revealed nothing untoward, nor did
the Event Viewer. Rebooting had no effect.

I shut the machine down with a view to looking inside, and noticed that the
little LED inside my Readyboost USB stick was flashing away rapidly. With
the PC switched off! Presumably this USB port remains powered even when the
PC is shut down. (It powers down only when you actually use the switch on
the back of the PSU, or unplug the mains lead, of course).

Anyway, I unplugged the USB stick, started up my machine and the problem was
instantly cured.

Clearly the USB stick had got into some kind of internal muddle, presumably
generating lots of interrupts and stealing processor time. Whether it's an
internal fault, or Vista sending it something which upsets it, I've no idea.

Whatever, I found it worked fine when I plugged it back in, so obviously
unplugging and replugging is all that would have been necessary to reset it.

So, if your machine has these odd stutters and freezes, try unplugging your
Readyboost USB stick!

I have the exact situation and continue to have that problem. Mouse is
unresponsive for two to 5 seconds. My only issue is that I don't have a USB
stick plugged in. Done everything that has been suggested on this board to
no avail.

I had a similar problem. My mouse, an optical 'laser' kind, was acting as a
ball mouse that was dirty - sporadic, I couldn't control it. There's really
nothing to clean and after spending some time with Logitech on the phone it
was determined that the optical part was bad. I did learn something that I
will pass on. I extended the usability of that mouse by shining a
flashlight in the hole underneath - the opening for the optical part. That
gave me another three days of use until the replacement arrived. That
'boost' of the flashlight returned the mouse to normal though only for a few
days.
