I booted a machine with a USB and a PS/2 keyboard from an i386 Intrepid alpha5 USB drive, with break=premount. panic() should run (after the modprobe for ps/2 keyboards):
if ! grep -q '^H:.*kbd' /proc/bus/input/devices ; then # no keyboard? Try USB. modprobe uhci-hcd modprobe ohci-hcd modprobe usbhid fi The line we want to match with grep is H: Handlers=kbd (that line has a trailing space.) In a fully running kernel, the line is e.g. H: Handlers=kbd event1 It's ok to load both USB modules, esp. since this only happens with break=whatever, or some other panic. So they won't be loaded for most people's normal boots. When we're trying handle errors, it's better to be safe. And it won't load anything extra if a keyboard of any kind is known to the kernel, thanks to grep on /proc/bus/input/devices. I'm not aware of USB host drivers other than ohci and uhci; They should work for almost all hardware ever. ehci-hcd isn't needed for keyboards, and is not sufficient for using them. I guess it _only_ handles USB2.0 HighSpeed devices. After modprobing both USB HCD drivers, I exitted from the break=premount shell, and the boot continued normally from my USB drive. ehci-hcd was loaded properly and both keyboards work after boot.
