I don't know anything about how the buffering of read data is actually done
in the devices, but what about submitting a bulk read URB with a length of,
say, 256bytes?
If the device actually has more than 64bytes buffered, it is possible that
one URB can read it all. The Anchor chips for example have an optional
double buffering mode for bulk endpoints, allowing back-to-back transfers
with zero delay.
