Current code has an arbitrary limit of 32 bytes. It can be raised
with a recompile, but it's always there. In case of a storage device,
one URB can transfer a lot. You can see a 128KB transfer if your
memory is not fragmented.

That should be no problem, just rebuild.

In general, this was supposed to be handled by a different API,
but nobody was sufficiently interested to do the requisite work.
