If you use Isoc pipe it will probably be serviced around few milliseconds, but in theory the request can be just dropped on the floor, USB is designed this way. If you use other pipes then the transfers can take longer, depending on the type of transfer. Maybe 10 ms, maybe even 100 ms ... These transfers are guaranteed to succeed, but no obligations on "when" part... Would you like to define your timing tolerances? Dmitri
