I have a problem connecting a PS2 keyboard to a notebook computer  using the USB port. I have a PS2 to USB adapter but when I connect to the notebook (Windows XP installed) it shows "Unknown Device". It would be easier to go buy a USB keyboard but the one I have is a "Russian keyboard" that I like. I tried using the PS2 to USB adapter with a standard English keyboard but the result was the same.

Do you have PS2 to USB coverter or USB to PS2 adapter. I believe you are talking about USB to PS2 adapater. You nee to install the driver for USB to PS2 Adapter, in jernal xp should take automaticaly. But for some reason its not taking itselt. Try using some other USB port and insert in USb after machine is booted completely. There you can find if the device is installing its drivers or not. If windws can find the new device when you attach it, that means the problem is with driver. very rare chance of failure of adapter itself.

Wrong type of adapter.

You are trying to convert a PS2 keyboard to USB.  However the adapter is incorrect.  You probably have a passive adapter when you need a converter instead.

See http://www.clickykeyboards.com/index.cfm/fa/items.main/parentcat/11298/subcatid/0/id/124184 for more information on the right type.

Simply try buying a new adapter of a different brand. Some of this adapters are cheap, but not very compatible with new motherboards.
Don´t kill your brain trying to "solve" the problem, but just try a diferent adapter. I use those a lot in my business and had problems a lot too, but all went fine when I found a good adapter (with a recognized brand)

I belive that my comment in the link above describes a solution to the problem.

His symptoms are using the wrong adapter.  If he uses the adapter as described in the link the problem should be fixed.

The explanation and link I supplied describe his problem and the solution to it.

I believe he is using a passive converter when he should be using an active converter.  The link I supplied goes into gory details about this.
