[App_rpt-users] Moving URI between USB ports.

Hi Everybody, In an attempt to fix a random "motorboating" audio issue on transmit I have with my new AllStarLink node, I fitted a PCI USB2.0 board (NEC chipset) to the computer. CentOS found the new card fine. I shifted my URI to one of the new USB ports and everything seems to be working... EXCEPT I am not getting any transmitted audio. Receive audio is fine, the radio will key up OK... but I get no telemetry tones nor any incoming audio. What needs to be done when you move a URI to another USB port? Why would receive audio be fine and transmitted audio not? Please be gentle, I am still a little green with this new stuff. Michael. VK5ZEA
