When booting a default kernel e.g. standard install cd the KVM over LAN
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

Anyone got any ideas why USB would break the IPMI keyboard?The IPMI keyboard is a USB keyboard. It seems to work OK on a box running 7.0: port 6 addr 2: high speed, self powered, config 1, Multidevice(0x0002), Peppercon AG(0x14dd), rev 0.01 ukbd0: <Peppercon AG Multidevice, class 0/0, rev 2.00/0.01, addr 2> on uhub3 The same box running 6.2 did not connect the device as a usb keyboard. -- Erik
