USB transfers are 64-byte packets.

Granted. But if you assume that the seek time(1) of a floppy drive is always
going to be enough to cover the latency of starting a USB transfer, you
should be able to buffer enough data at the device end to ensure you don't
get a buffer under-run during a sector read.

(1) I would imagine the timing would have to be fairly tolerant for seeks
given the variable step times for different drives???
