Thanks for doing this work, Matt!  I appreciate it.

You say that these apply against 2.6.38, but recently a lot of xHCI
changes went into Linus' tree to support USB 3.0 hubs in 2.6.39.  Will
these patches still apply against Linus' latest tree?  If not, I suggest
you base your patches against Greg KH's usb-linus branch, as that's my
tree base:

http://git.kernel.org/?p=linux/kernel/git/gregkh/usb-2.6.git;a=shortlog;h=refs/heads/usb-linus

Also, I haven't read too far into the patches, but the first patch seems
to have several one or two letter variable names, like "f" and "di".
Can you make those variable names more descriptive?  Thanks.
