RE: Information about the sampling rate of the RTLSDR driver

Thanks for your answer. I increased the size of the output buffer but, I'm still having the problem. With a buffer of 262144 bytes, at 2.048 Ms/s, it should be full every 16ms, but my program indicates 64ms. Could it be due to a limitation on USB ports, or on my Device (Terratec Cinergy TStick RC) ?
