=46rom these dmesg lines you posted in your first mail it looked that is to=

short time for kernel to recognize the usb device. I had similar problems o=
n=20
mips RS/RSPRO boards and had to use small patch to make the delay longer. I=

admit that I didn't know of kern.cam.boot_delay that time and haven't tried=
it=20
on my boards.
I don't know the real author of that patch.
Additionally I'm booting my board using ufs label this way:
