Hello Weewx Users,
I have been using weewx on a RPI4 for quite some time now (a few years). I
am using an RTL-SDR dongle to capture data from an Acurite Atlas weather
station. I am also using a BME280 device for pressure. Things have been
pretty stable for years. However, recently I am getting these errors
nearly daily:
ERROR user.sdr: cb transfer status: 1, canceling...
ERROR user.sdr: LIBUSB_ERROR_NOT_FOUND: Entity not found!
Check your RTL-SDR dongle, USB cables, and power supply.
ERROR user.sdr: WARNING: async read failed (-5).
ERROR user.sdr: Library error -5, exiting...
Exception in thread stdout-thread:

Rebooting the RPI generally fixes the issue without the need to touch the
USB cable. I had a USB extension cable between the RTL-SDR and the RPI so
I tried bypassing the extension cable by plugging in the RTL-SDR directly
into the RPI, but I'm getting the same results. I also tried different USB
ports on the RPI also with the same results.
Versions:
Debian GNU/Linux 12 (bookworm)
Linux raspberrypi 6.1.21-v8
weewx-5.1.0-4
rtl-sdr-0.6.0-4
Does this mean it is time for a new RTL-SDR device or is there any firmware
needed for the RPI usb ports or maybe a firmware update for the RTL-SDR
device?
The issue is getting annoying because I don't know when it will error out
again and need a reboot to fix it.
Thanks in advance!
