I have looked at EHCI sources in 2.5.63 and have some questions.
For each element of urb->iso_frame_desc there is one allocated iTD. It looks like that one iso_frame_desc element should describe all transactions in one frame (not uframe) because one iTD can handle eight uframes.
But in itd_fill is iso_frame_desc[x].length compared to endpoint's max packet size which describes one uframe. Also in itd_complete is iso_frame_desc[x].status is updated in according to itd->hw_transaction which describes one uframe too.
Does in means that this code can handle only iso endpoints with interval 8 i.e. one transaction (no high bandwith) per frame?
