writing usb drivers under 8.x

[Jim Bryant]

thanks.  am doing that now.

I already have one patch for this one....

what kind of idiot defines a constant assignment for a 32k buffer as a 
15 bit left shift of 1?

clever, yes.  but in production, stupid.

a constant should be just that, a constant, and thus require no 
computation at runtime.

i'm old school, and what a lot of kids don't understand today is that 
small and efficient is still as applicable today as it was then.
