Yes, UMASS and UKBD should work from the debugger.

hmm...is it necessary to add any extra options to the kernelconf? because when
i hit the panic key-combo under r196037 i'm still not able to use my usb
keyboard. i have the following debug related options in my kernelconf:
options KDB
options BREAK_TO_DEBUGGER
options DDB

This is maybe because the CPU is in the USB stack already. What is the
backtrace?
If you use the panic sysctl, does the keyboard work then?

just tried settings `sysctl debug.kdb.panic = 1`. if i use this way to enter
the kernel debugger my usb keyboard works. if i type continue however the
kernel panics and the kernel debugger gets yet entered again, but without the
keyboard working.
i don't know how to produce backtraces since

if i understood it correctly the reason a usb keyboard cannot be used in the
kernel debugger after a panic is that we can't be sure the panic didn't happen
inside the usb stack so the whole usb stack is discarded at a panic.
maybe this would be a solution:

just found this wiki: http://wiki.freebsd.org/USBTODO
so making ukbd giant free has a high priority? very nice. :)
