Measurement of exclusive $B\rightarrow X_u l\nu$ branching fractions using semileptonic tags

Using 210 fb$^{-1}$ of $\Upsilon(4S)$ data collected with the BABAR detector at the PEP-II storage ring, we report the result of a measurement of branching fractions of exclusive $B\to X_u\ell\nu$ decays. The accompanying $B$ mesons are tagged with semileptonic $B\to D^{(*)}\ell\nu$ decays.
