Re: USB support + Supermicro IPMI KVM = no keyboard
Steven Hartland
keyboard on Supermicro's IPMI modules refuse to function. Once installed
if we build a kernel without USB all is good.
So two questions:-
1. Can usb support be disabled from the loader?
2. Anyone got any ideas why USB would break the IPMI keyboard?
Regards
Steve

You could try hint.kbdmux.0.disabled="1" - see kdbmux(4) for details.

Thanks for the idea Max no go unfortunately, also tried:-
hint.usb.0.disabled=1
hint.uhci.0.disabled=1
hint.ohci.0.disabled=1
hint.ukbd.0.disabled=1

Maybe the keyboard is done via USB and the BIOS sets legacy support
for USB keyboards, which is disabled by USB drivers to handle it
natively.
You have to know that USB controllers can emulate the old 8042 driven
keyboards in hardware, but this won't allow using other USB devices
at the same time.
As long as FreeBSD isn't touching the USB controller the emulation
would be kept.
You should take a lock into the BIOS setup if you can change USB
keyboard legacy support.
And you should lock into boot messages if there is a non working USB
device found.
The USB legacy thing is just an assumption - it could be something
completely different as well.
