Hi,all!
I use streamer to read data from USB board(3014).As the source data is increase packet by packet I find that I miss some packet by detecting the header of the packets.but I examine all the packets transmited in USB Analyzer, It shows all the packets has reached the PC host correctly. The length of packet is 16KB and I choose 2 packets per xfer.
After debuging the streamer project I find that the reason of missing packets is that the finishdatatransfer() fail. how can I get the error code so as to analize the reason. And to my surprise sometimes I can read data correctly and sometimes miss some data.And if I choose larger num of packets per xfer I will miss data more frequently.
I am confused by this probelm for a long time. could you help me to fix it or give me some suggestions?
Thanks and Best Regards
