Regular PS2/USB keyboards autodetect which interface they are plugged into and change their signalling/power accordingly. I'm guessing that the Ergo 4000 is using a new controller chip from the previous models and does not support this dual mode of operation. Seems a little odd, the savings in that are going to be very very tiny (several cents probably). I wouldn't be surprised to see more going this route.
You may be able to get a PS2 port that connects to USB, but I don't think youd get a USB port that connects to PS2. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Hunter, Gary > Sent: 25 February 2006 18:49 > To: The Hardware List > Subject: [H] USB - PS2 convertor and Microsoft Ergo 4000 > > Hi, > > Last week I got a Microsoft Ergo 4000 keyboard.
