Retrying wouldn't do much good now would it? I'd say that devices needing such a clear-halt are worth a quirk flag.

If the quirk is set, you have the answer. :) I suggest that when ep0 stalls you look at its endpoint status to see if the HALT bit is set ... if it is, set the quirk flag. - Dave ------------------------------------------------------------------------- Take Surveys.
