Are you talking about d2go? It came with Talks 4.5? It did not upgrade with Talks 5. This means you can play DAISY files on your phone. The Plextalk is a different player. It does make a musical sound when you turn it on. I an not sure what you are referring to in terms of USB in relation to your computer. Only think I can think of is that you may be talking about transferring DAISY files via the USB to your phone. Eleanor -original message- Subject: [talks-uk] a daisy problem sorry.
