That is exactly what I did.
The problem is in the message "no usb disk",  which is confirmed by
at% ls /dev/sd*
/dev/sdctl
at%

I believe my 9pccpu kernel is sufficiently recent.
--rwxrwxr-x M 221 sys sys 2368300 May 18 07:16 /386/9pccpu

and my script in creating bootable usb disk is as follows:
disk/partfs /dev/sdU0.0/data	# create /dev/sdXX
disk/mbr -m /386/mbr /dev/sdXX/data
disk/fdisk -baw /dev/sdXX/data
disk/prep -bw -a^(9fat nvram) /dev/sdXX/plan9
cp /dev/sdC0/nvram /dev/sdXX/nvram
cp /386/9loadusb 9load
cp /386/9pc 9pc
cp /386/9pccpu 9pccpu
disk/format -b /386/pbslba -d -r 2 /dev/sdXX/9fat 9load 9pc 9pccpu plan9.ini

If the problem is only to me, I am disliked by 9pccpu kernel.
