Various older Linux HCDs used to do that. It should be "mostly harmless", but it's more polite if your HCD makes sure to issue the status stage unless it gets a STALL. There's peripheral hardware (and firmware) out there that for some reason doesn't handle SETUP packets correctly if the preceding transfer hasn't properly terminated. - Dave ------------------------------------------------------- SF.Net email is sponsored by: Tell us your software development plans!
