usb keyboard

[Jan Muller]

Synopsis:
During initial installation of FreeBSD 6.2-RELEASE i386, OS does not 
recognize the USB keyboard after third stage boot.

Environment:
installing rel. 6.2 from CD, HW is Dell OptiPlex 745 SF with USB 
connected keyboard and mouse

Description:
when installing from CD, keyboard is recognized during initial boot 
phases, which allows escape to loader prompt from beastie menu and various 
interactions from loader prompt. However, when boot continues to 
sysinstall (the first program is country selection), keyboard is no longer 
effective.

the loader shows usual variables, such as
hint.atkbd.0.at=atkbdc
hint.atkbd.0.irq=1
hint.atkbdc.0.at=isa
hint.atkbdc.0.port=0x060


when run without any changes, loader finds various usb and uhub deviecs, 
and during hw scan states also 
kbd0 at atkbd0 
and then runs sysinstall (inoperative since keyboard is not recognized)

when these four hints are unset at loader prompt, the statements such as 
kbd0 at atkbd0 (and several other ones) are not there any more.
Nevertheless, the country selection program still does not accept any 
keyboard input.

The only related info in FAQ was a statement "FreeBSD supports USB 
keyboards out-of-the-box",  which turned out not to be the case here :-(
The FAQ answer then proceeds to describe how to enable USB keyboard 
support using kbdcontrol command, presumably on an already installed 
system ...

Could you help me with this problem?
