I acquired a wireless laser mouse, probably produced by Teac Co. (or at least so is written on the label)
The driver diskette was faulty and I looked for a driver on the Internet, but in all the sites of Teac I couldn't find any reference to such product.
The mouse works fine even so, but I would like to know if this is really a product of Teac or some falsification or what.
And how can a driver be found, if happens that it is necessary for some function?
Please advise
Thanks

I would like to know if this is really a product of Teac or some falsification or what.

TEAC has been a big player in the electronics industry for decades, but that does not mean they don't outsource their mouse manufacturing to some 3rd party supplier.

And how can a driver be found

If you mean how is Windows working anyway, that's because Windows knows how to talk to any mouse using basic mouse functions. You generally only need specific drivers to enable special features the mouse might have - like a second scroll wheel or extra buttons.

If you mean how can you find specific drivers for that TEAC mouse - you need to start with the model number of the mouse, then plug it into Google and you may get lucky.
