Now I better understand why you wondered whether there is a non-blocking call option. Sending the first "S Ii" does not return until either timeout or a received "C", right ? That way you simply cannot send the second "S". Does pyusb not offer any non-blocking submissions ? Karsten -- GPG 40BE 5B0E C98E 1713 AFA6 5BC0 3BEA AC80 7D4F C89B
