USB zero-length delimiter transfers

I'm writing my first USB driver and now have to deal with the vagueries of
transfers that are a multiple of the max transfer size and the need to send
zero-length delimiter transfers. I have implemented something and it appears
to work, but my major concerns are:

Did I do it right?
Will my driver work properly on a USB 2.0 bus?

Can anyone point me to a good source of infomation on this topic?

Thanks for reading,

Mike

if it is working for you now, it should work on usb 2.0 w/out issue. you
can always hook up a CATC and verify what is going on at the bus level.
