I recently encountered an intriguing challenge while setting up Home Assistant on my Raspberry Pi 4B using a USB flash drive for booting. The system worked flawlessly initially, but plugging in a second USB device caused a complete system freeze. This unexpected behavior left me puzzled, as both the GUI and SSH access became unresponsive.
After some research, I discovered that the issue might stem from the USB boot configuration. I explored the possibility of USB port prioritization but found no evidence supporting this theory. Determined to resolve the problem, I decided to experiment with adjusting the USB power settings and revising the boot order through the Raspberry Pi’s configuration tools.
To my delight, tweaking the power management settings and ensuring the primary USB device was recognized first resolved the issue. Now, I can utilize multiple USB devices without any hiccups. This experience underscored the importance of thorough testing and the value of community resources in troubleshooting.
If anyone else encounters similar issues, I recommend checking the power management settings and verifying the boot order configuration. Happy tinkering!
