I just got my pocket pod and in setting it up and reading the instructions this is one of the fist things I read that might help you out.
The following USB ports are known to cause Pocket POD to spontaneously reset its drivers and
reboot itself when accessed by connected MIDI software:
All USB hubs including many USB ports built into laptop PCs,
Mac Tower: The front USB port
Macbook: The back (left) USB port
Macbook Pro: The right USB ports
PLEASE ENSURE YOUR POCKET POD IS CONNECTED THROUGH A RELIABLE USB PORT BEFORE PROCEEDING!
Everything checked on the list above? Great! Now you should quit any MIDI port using music software you
have running before you launch the program for the first time – This will avoid any possible conflicts between
Vyzex and your other MIDI software on the program’s maiden voyage.
Hope this helps you. Can't believe no one has responded to you in 3 months.;o(
