Hi Edouard, I found out about the send and receive buffer sizes. The person who told me would not like it to be publically known that he told me.
Receive buffer: 64 * 53 is the least common multiple of 64 (packet size of the bulk endpoint) and 53 (ATM cell size). That way there is no wasted USB bandwidth. But you can use other sizes too. Sending: the send buffer can be up to 64k. Duncan. Liste de diffusion modem ALCATEL SpeedTouch USB Pour se désinscrire : mailto:[EMAIL PROTECTED]?subject=unsubscribe
