Finally, we can send and receive some data. The pipe references are in the same order as the end points that appear in the Bus Probe tab of USB Prober. In our case, pipe 0 is the default control endpoint (does not have an endpoint descriptor and will not appear in USB Prober), pipe 1 is the bulk data output endpoint, and pipe 2 is the bulk data input endpoint.
For some reason, if we read less than 64 bytes I/O Kit returns a kIOReturnOverrun error. Coincidentally, the max packet size of the bulk input pipe of the device is also 64 bytes.
