No problem is same. Older kernels have another troubles.
2.6.22-1-mepis-smp
Quite stable. Have oops sometime inside evdev. Support up to 16
USB keyboards, where 4 hubs are plugged into PC and 4 keyboards on
each hub. Any hub cascade support only 4 keyboards, where 5th or more
is registered but don't send input events. Oops inside evdev , when
USB keyboard unplugged. No slow down even all USB keyboards does
not work properly. My be this one support more than 16 keyboards, but
i don't have PC USB ports enough.

2.6.24-7
4 keyboards per port. If plug in 5th tend to total slow down with this one:
usb 2-1.1.1: reset low speed USB device using
uhci_hcd and address 17
5th - means 5th keyboard in USB hub's cascade, which is plugged into
single PC USB port.

2.6.26
4 keyboards per port. If plug in 5th tend to total slow down.

2.6.27-rc3
Sorry Randy i cannot repeat Your achievement. This worse of all tested
kernels. I got working 3 USB keyboards, when i plug in 4th, all keyboards,
include PS/2 stop working. Kernel does not hung up. I can reach box
via net. dmesg , /proc/bus/input/devices attached. lsusb hung up.

Please notify me , if i should use 2.6.27-rc2 !
