Most likely the device does not understand the command/data your host program sends to it. For example, the device may need some initialization to start the Bulk IN transfer. Do you know the communication protocol of the device? If not, you need to start with some reverse engineering. BTW, for starting, it is easier to use the simpler synchronous API to get the basics right and then you can use the asynchronous API. -- Xiaofan ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
