It turns out that usb boot is more complicated than it needs to be.  With
readparts= the partitions are set up automatically, but then they are thrown
away again, I think because partfs is being started more than once.  I will
leave it to the original authors to look at, but a workaround is to use sdB0part
as Erik suggested.  I find this cmdline.txt works for me:

sdB0part='fossil 204864 1804192' bootargs=local!/dev/sdXX/fossil ipconfig=

where the sdB0part numbers are found from 'grep fossil /dev/sdXX/ctl'
