I have done all the alpha and beta and final 10.04 and have had no trouble with
my Logitec wireless keyboard, but I have had trouble with my usb wifi adapter
not switching on when I boot up. I have not used a wired keyboard for a couple
of years.

I would suggest selecting a higher priority usb socket connected direct to the
mother board and not via a usb hub which may not be active in the early boot
sequence. (Check any diode indicators on your wireless adapter)
