I have a relatively new (<1yr) PC without PS/2 keyboard & mouse connectors. I've accumulated 4 USB to PS/2 adapters. Three are just 6" cables with a USB male on one end and a PS/2 female on the other. The fourth is similar, but has a large oval-ish thing in the middle of the cable. My MS ergonomic keyboard has a PS/2 connector and will not work when connected using one of the three plain adapters, but will with the fourth. I'd like to understand a) why, and b) where to buy a couple more of the adapters that do work (for another project). Any help from the incredibly knowledgeable PLUG-ers will be gratefully appreciated.
