If you have spare hardware, are you able to remove and bypass the hub to determine if you still see the same u-boot issues? Conversely, are you able to connect this hub (for example a dev kit or a commerical hub with this chipset) to the MPC5200 to see if you still have issues? I'm trying to determine the hub's role, if at all possible. Other than that, I'm a little short of ideas. Potentially some timing since (IIRC) the mpc5200 is full-speed not high speed? I'm kind of clutching at straws here. Maybe someone with a bit more knowledge about USB can make a more informed comment. -- Damien _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
