Re: limitations of using multiple RTL-SDR dongles simultaneously

Nice MR Markgraf ! It works perfectly!

Thanks you very much! :-)

Thanks also to MR Muller for the Linux distrib that I did not know GNU_Radio-Live-Hamradio-binary.iso

Good continuation!

Is this a limitation of the RTL-SDR library or the kernel driver? Do we have a solution to get around the problem?

This is a limitation of the Kernel, as the maximum usbfs buffer size is set to 16 MB by default. In order to disable this limit, do the following:

echo 0 > /sys/module/usbcore/parameters/usbfs_memory_mb
