Re: filmscanners: What causes this and is there any easy solution ?



Anything USB will track better because of the higher sampling rate.
Unfortunately the MS USB mouse I bought didn't like the KT133 VIA chipset on
the motherboard. This is a common problem with Via chipsets see:
http://www.usbman.com . When I first installed the motherboard I couldn't
use USB at all with my Epson 1270 and the USB mouse & keyboard caused
periodic crashes. Eventually I gave up on the mouse and keyboard but I
managed to persuade the printer to work.

It's not entirely Vias fault though has my Casio camera has had absolute
zero problems from day 1.

If you have a PS/2 mouse, AT YOUR OWN RISK, you can overclock the sampling
rate. Never heard of anyone permanently damaging anything with this
procedure but I am sure it can be done (I have tried it before myself). If
you did permanently damage the PS/2 port you would have to use a USB or
serial port mouse - you  have been warned.
