Hi, I have tried the suggestions of this e-mail list and wish to return the results I have obtained thus far. My problem originated with setting up iListen. I have not got iListen to work yet since I have been concentrating on ViaVoice. The fundamental problem with my setup was that the USB hub was not powered. So I bought a powered USB hub and connected my microphone and sound pod directly to the port on the G4. I had thought a USB hub was like an Ethernet hub, silly me. I have noticed better accuracy but I don't know whether that is due to my getting better at talking to a speech recognition program or to bypassing the USB hub and connecting directly to the G4. My other peripherals now work however. Thanks for all the help. mike ps. I have G4 933 Mhz, 1 GB Ram Jaguar Mac OS X 10.2.6 Buddy /Gooseneck (non USB) mic connected to Andrea USB sound pod connected directly to a G4 USB port Belkin USB 4-port hub (powered) connected directly to a G4 USB port
