No PC stated. 34 years of HP PC and not one stated.
name and model number
the keyboard there above is HP relic PS2 keyboard.
it will only work on HP PCs and only old ones.with PS2 jack at rear.

try this tell the helper
what you have before you.
what OS is there windows 2000, win 98? what ?
what are you attempting to do, tell your goals.
eg: I cant enter my password in the windows, login screen (example)
tell what you are doing and what happens wrong.

do not not use a HP PS2 keyboard on a DELL
or the reverse PS2 is unique to HP.
there is no filter keys on the board.
in fact I have no idea what you meant by filters.

there are vast language modes for keyboards
some keyboards long ago had switch on the bottom to make it work with older PC.
some even run both USB and PS2 and had a switch for that.
on the bottom.

my guess is your using the wrong keyboard,

I have LS2208 PS2 and Nothing is send to computer

have you tried swopping out the cable? If that doesnt work I would just buy a new device. These are cponsidered consumable scanners. When they faile they tend to get replaced because they are so cheap

Yes, it will work. The scanner interfaces like USB and RS232 are Operation System independent.

Driver for v220 logitech mouse os win 98


I'm afraid the USB mouses will not work on windows 98, please use the adapter so it fits into a ps2 port. (the old mouse plug) then of course you can check the logitechs website if they offer any drivers for windows 98 but its very unlikely.

Actually I looked myself and the oldest they offer is xp.,en

so it would be a good time to buy a new computer, yours must be around 12 years old. considering that 5 year old machine is considered old, your 12year old machine is ancient.

Have a look at the HOST setting in your defaults. I set one of these to default and had the same result. I'm guessing it's because the HOST is blank on Default settings.
