how long would the host wait when a transfer with no reply

        The host launches a bulk in transfer,if the endpoint doesn't have any data all the time,then after waiting some time,the host still doesn't get any data, then the host would abandon this tranfer.

        now a question is how much time exactly would the host wait? and similarly how much is in the bulk out transfer and isochronous IN/OUT transfer?

        thank you!

It depends on the timeout value that you specify when you trigger the transfer. Please look at CyAPI.lib and CyUSB.dll documentation in SuiteUSB for more details.

Regards,

Anand
