Problem:
Periodically there is an issue 'unable to enumerate USB device' using an IoT device connected to the Raspberry Pi 4B.
The similar behaviour is also observed while using a USB-UART TTL converter (FTDI FT232RL).
The issue reproduces on different RPIs, including 3B+ and 4B models, 'bullseye' and 'bookworm' versions as well.
Replacing an USB cables also does not help. From time to time the problem occurs again.
Symptoms:
RPi does not recognise connected USB device.
Possible temporary solutions:
dmesg logs:
