Mine is the JMicron JMS578 cheapo (advertisement inside ![:x]( "Mad")
).
I used usb-storage.quirks=152d![:0578:]()
u in cmdline.txt to workaround poor behaviour.
But my main question is: do I still need the SDCard albeit the main page of software documentation states I can boot from USB. Maybe this is a ~new~ feature that becomes available for all Pi hardware platforms after an update to a newer firmware ?
I'm puzzled within SSD rootfs/boot/cmdline.txt that is empty but a warning stating "Don't Edit - It is moved to /boot/firmware/cmdline.txt" when nowhere in the SSD there is a firmware folder but the empty rootfs/boot/firmware ????
USB power is not the issue here because it worked with Buster
