USB connection to RTL device crashing, followed by Ethernet disconnection upon preparation for an observation on Raspberry Pi

Satellites & Observations Observations
1

After realizing that some observations were not served as expected, I tried to connect to my RPi and found out that I could not reach it.
After recycling it, I inspected the system logfiles and found out that the USB port (supposedly) of the RTL device was disabled alongside with the ethernet connection.
I am afraid that it might be something related to my NooElec SDR dongle that causes the issue on the USB port, which then triggers the disabling of the USB device itself and the ethernet along (I guess both USB and ethernet capabilities are provided by the same chip). After rebooting I double checked that the RTL was working nominal through the standalone-mode and now I am waiting for an observation to be served.
It might be that after days of continuous running the RPi or the RTL dongle got overheated?
Below I attach the part of the system log, where I figured out the issue.

Sounds like the USB hub built into the board which lets the USB based Ethernet and the USB ports work off the single port on the CPU is somehow crashing / turning off.

Hm maybe your single is somehow shorting? As as soon as it enable the whole hub crashes out according to that log.

No, I don’t think this is the issue.
After all the dongle has been working all the time and every pass is served nominally, but then all of a sudden this issue appeared and after rebooting the RPi went back to nominal.
