I have just got a Trust MI-6950R laser USB wired mouse to use on my shiny new Vista Laptop (Acer 9303). The docs state plug it in first, let it auto detect and start working, and THEN install the software from inclosed disc. Vista finds a driver, not sure if it's pre loaded or found it on the net, starts to install it, then pops up an error:
Problem encountered installing driver. The driver installation file for this device is missing a necessary entry. This may be because the INF was written for Win 95 or later. Visit device website for driver software.
So I downloaded the driver from here (click here), chose the Vista 64 bit one (is that right??) but it still wouldn't work. Tried installing the software from the disc, still wouldn't work. Tried un-installing all the software to start a fresh, couldn't un-install one of them, and had to do a system restore to get back to where I was !!!!
All this time, the mouse wouldn't work at all. Not even as a very basic HID device. The box has a 'Certified for Vista' logo on it so I know it SHOULD work.
