That either means 1) someone scribbled over it 2) the xfer is pointing in the wrong direction or is not initialised 3) there is a bug in the USB code that does notset actlen correctly in some cases, but I would expect it to 0 in that case. I'll have to have a better look to see what is happening. Nick
