Hello. I have an issue with reading data from the USRP B200 on Windows 10. When I run the benchmark_rate with a 20 MHz reception bandwidth, I see losses of more than 50 percent. However, there are no losses during transmission. I have followed all the instructions, including modifying the registry and disabling power management for USB. The same issue occurs even when using an external power supply. Can you please advise on what the possible problems might be? On the same PC, when using Ubuntu, I can receive 50 MHz with almost no losses.

Sounds like the USB host controller's Windows driver and/or controller firmware coming with that driver leave things to be desired. I honestly don't have a good recommendation there, other than to make sure your Windows drivers are up to date – Windows is not per se worse than Linux at USB.

I have same problem. Please have anyone clue what should I do ?

Im using MSI katana UF66 11UG: CPU: 11th Gen Intel(R) Core(TM) i7-11800H RAM: 16 GB GPU: Nvidia RTX 3070 I think its pretty good laptop for this job (I want only receive IQ data and store it in wav files). I have configured virtual enviroment (Ubuntu 22.04) so I can try linux commands to "benchmark" my laptop to see if it is able to work with B210. I found tutorial how to check RAM speed. output: wmic memorychip get speed Speed 3200 3200 and in Device Manager I got in Display adapters >> RTX 3070 >> max link speed says 00000004 (gen 4). Can I check something else which can be a problem ??? Thank you for your help, your time and efford. It helps me a lot.

Unfortunately, this has no effect on losses. пн, 25 вер. 2023 р. о 09:56 Marcus D. Leech <patchvonbraun@gmail.com> пише: > On 25/09/2023 01:28, Olo via USRP-users wrote: > > I have same problem.

 My output from benchmark_rate --rx_rate 20MHz:

 You could use the "num_recv_frames" device argument:

 num_recv_frames=256

 See if that makes a difference.

I'll make dual boot laptop with Windows 10 and Ubuntu 22.04 and maybe it will work.
