USB problems in 2.2.14pre9

From: brad allison <hidden>

I'm seeing the strange problem when I type cd really fast that it comes
out as cdcd or cdc .

Other people who's used my keyboard see the same thing, but you have to
type it really fast.  It seems almost random.

I didn't see the problem until I switch to 2.2.14pre9 and
Xpmac.rage128.usb.rev6 .  I backed out of Xpmac.rage128.usb.rev6 to
XF68_FBDev because of cut-and-paste problems with Xpmac.rage128.usb.rev6
and I'm still seeing this weird "cdcd" problem.

Anyone else seeing this?

Oh yes, I am using a USB keyboard right now.  It seems to happen whenever
more than three keys are simultaneously down...  When the fourth key is
pressed, it isn't reported.  At this point, releasing any of the four keys
causes duplicated key strokes to be reported.  Strange.

Using a more current stack (2.3.40) I can use up to 6 keys (ie press 'em
one after another and the last pressed one works) and the 7th is ignored.

Hmm, I also noticed that some combinations of keys will glitch on the
3rd keystroke.  Thinking about back when I learned about low-level
keyboard stuff, I think that some keyboards can only handle a certain
number of keys down or they report a "too many keys" code.  Perhaps this
code is not being handled correctly?  Or, maybe I'm just on crack.  (Hard
to say considering the way my day is going today)
