this to the maximum filesize (in bytes) for the buffer.
Default is 4 MiB if undefined.
DFU_DEFAULT_POLL_TIMEOUT
Poll timeout [ms], is the timeout a device can send to the
host. The host must wait for this timeout before sending
a subsequent DFU_GET_STATUS request to the device.
DFU_MANIFEST_POLL_TIMEOUT
Poll timeout [ms], which the device sends to the host when
entering dfuMANIFEST state. Host waits this timeout, before
sending again an USB request to the device.
