Hi, I am not sure if this helps. Please run the following commands whenever you experience this issue with B210 and let me know if this works.
cd /usr/local/lib/uhd/utils sudo ./b2xx_fx3_utils --reset-device ______________________________ regards, Venkatareddy ________________________________ From: Francisco Gallardo lópez <[email protected]> Sent: Wednesday, August 16, 2023 17:56 To: Marcus D.

It happens sometimes, but not always. I would say mainly when there is a power outage or similar, but not always. For the sake of testing, I just rebooted the remote machine. This time it appears in both lsusb and uhd_find_devices upon reboot. As said, I am not sure about the root cause. So it is complicated to tell. When that happened last time, I did not check lsusb, but uhd_find_devices, and the system was not seeing the USRP. I guess lsusb would also not show the device. I will check the thread Eden pointed out. Thanks Fran El mar, 15 ago 2023 a las 16:59, Marcus D.

For example, on some hardware, the system cannot see the device on reboot, and you have to replug/power-cycle for the system to even see it. When this happens, does it show up in "lsusb" ? _______________________________________________ USRP-users mailing list -- [email protected]<mailto:[email protected]> To unsubscribe send an email to [email protected]<mailto:[email protected]>
