Same concern here: the message you quote is the only one mentioning
-EILSEQ, and that developer only appears to remember someone else
Please understand that putting a workaround like that is usually frowned
upon, because it may hide a real problem. So I think we need to try to
accumulate some statistics on the matter, and to isolate the source of

be a firmware bug, it can be reported to ADI and hopefully fixed by
Maybe you can get people at eagle-usb.org who have a high enough
connection speed to try to use your driver in both bulk and iso mode
without the EILSEQ workaround? (Naturally I also suggest trying with my
