I'll hope to see it in pre2! :) Indeed.

It enumerates reliably at full speed too, for starters! My Rev B board wouldn't enumerate (at full or high speed) reliably. It now (with -rc2-gregkh-1) enumerates reliably at high speed. I'll give it a spin at full speed today. > As for test apps, I've tweaked the "bulk src" example a bit > so that it's a straight source/sink, and it's been invaluable > for testing bulk and interrupt transfers.

I'll probably load the Keil tools, but I really want to be able to build with sdcc. So the header would help - can you send me that too.
