Tonight's Raspberry Pi 5 update broke the USB function.
Could not boot from USB SSD, boot up froze part way finished, when loading USB stuff
If booted from a uSD when a USB SSD was connected the system immediately froze.
Downgrading to linux-rpi-16k-6.6.37-2 and linux-rpi-16k-headers-6.6.37-2 fixed the problem.
I haven't checked yet if Raspberry Pi 4b has the same problem.
linux-rpi-6.6.39-1
linux-rpi-6.6.39-1
Pudge
EDIT:
I have tested the RPi 4b and it is not affected, it works fine.
Further testing on the RP i5 with linux-rpi-16k-6.6.39-1
if you connect a USB SSD to to the RPi 5 USB 2 port it works OK.
If you connect the same USB SSD to the RPi 5 USB 3 port it immediately freezes
and fails to reboot.
