Hi, > - CPU consumption was not an issue (sorry for wrong info. my bad) > -- but network throughput performance is bad > - USB controller on the CPU is not fast > -- max throughput for USB memory read is about 50 Mbps on our test > -- max client mode transfer rate is about 20 Mbps (at best) Ah ok, as CPU consumption is not the problem, then I better understand the problem. My previous patch missed one fix for a return value. Could you try this one. > BTW, we are in the big holiday week[10] right now. so please bear > with us. we might not reply promptly. Not a problem.
