Hi Cristian,
someone else being able to run the same flow graph doesn't help you at
all, sorry. It does work in general, pinky promise.
USB3 system performance is often nontrivial to achieve, as you (sadly)
noticed. Usually, performance issues are a combination of USB host

Hi all.
Thanks a lot for your help.
What do you think about it?
If I type lsusb in the terminal i get it:

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Hi Marcus.
Thanks a lot for your answer.
Could you please run the ieee802.11 transceiver flowgraph of Bastian ? And
please, tell me if you get overruns, without modifing the number of buffers?
Really you would help me a lot. Because i don't understand why i get
overruns when other people don't a
install (apt) cpufreq-utils and indicator-cpufreq, you'll get a UI icon to
set the CPU to "performance" mode.

Gut feeling: your computer might have adaptive power saving, so that
your CPU is scaled down sporadically, and then has a hard time

Hello Cristian:
If you use Ubuntu 16.04.2, the kernel is 4.8, which should be fine.
The specific USB controller is also very important. The Intel controllers
work best. Which controller do you have in your system? (run "lspci")
What flow control errors are you seeing? Are there any overruns ("O"
HI all.
I was writing to the forum a time ago because i have missed packets when i
build a simple flow graph in gnu radio and set the sample rate over
20Msamples/s.
The conclusion was that i had to review my USB 3.0 drivers but i'm working
on ubuntu (16.05) and the only way to change the drivers
