update to 2.6.11 interface changes

[Roman Kagan]

  Hi,

Now that 2.6.11 is out, we are faced with a necessity to support the
USB interface changes, although minor, between 2.6.10 and 2.6.11.  In
particular, now USB device descriptors are maintained in little-endian,
so all uses thereof have to be adjusted.

I suggest, instead of cluttering the code with #ifdefs, branch the
current version as, say, linux-2-6-10, and update the HEAD to the 2.6.11
interface changes.

Is everybody ok with this?

Roman.
