Yes this is definitely a "feature" of USB in DOS. It is not really supported, as mentioned on my site. Most PC BIOSes do have rudimentary USB DOS keyboard support but is really only for configuring the CMOS menus etc. I have found for some reason that Award Bioses slow down noticeably when using the non-numeric-pad arrow keys. USB is best avoided in DOS and is really only for Windows use. This problem will not happen in Windows.
