Re periodic transfers. I've tested 2.6.1 yesterday (yes, I've got comedi finally working under 2.6). One interrupt transfer works fine. Two transfers together not.
With which controller driver -- EHCI, OHCI, or UHCI? (If it's a full speed device, you might need to use EHCI through a high speed hub.)
I've seen that there's a patch around for periodic transfers. Has it been applied to 2.6.1? If not: do you (or anybody in this liste) have it? Can you send it to me?
I posted three patches, mostly for highspeed ISO on 12/29; that may be what you're thinking about. Not yet merged. Patches to teach EHCI how to build a proper interrupt schedule tree (like OHCI) haven't yet been updated recently.
