If you're thinking of plugging an old keyboard or similar into a newer computer, think again. Device. You'll most likely need an externally powered USB hub for it to work if that's all. The description should probably emphasize this fact better as it applies to 99.9% of products with a PS/2 connector. Without exaggerating, there is only a very small number of products for which this would really make sense.
