If you look at bootcmd_usb you'll see something like "ext2load usb
0:1".  0:1 defines the device and partition.

Unfortunately, I don't know whether you can force any consistent
device naming in u-boot.  I suppose you could run:
 ext2load usb 0:1 ....
 ext2load usb 1:1 ....
and in some cases the first command would fail and then the second
would succeed (or the other way around).
