Just for the record, I use a classic IBM clicky Model M with a ps2/usb
adapter, and a very cheap generic chinese usb keyboard, both problem
free without any external hub.

Patch /n/sources/patch/maybe/usb-short-desc makes a lot more keyboards
work (especially some with hubs).

While working on the pi2, I have discovered one glitch which also seems
to be the case on the B+ but not the B or A: after rebooting with the
"reboot" command (as opposed to resetting the power or using ^t^tr)
the keyboard won't respond without being unplugged and replugged.
Perhaps the built-in 4-port hub on these pi models needs some sort
of reset which the 2-port hub doesn't.
