I want to connect multiple PhoneTree hardware units to my PC, but I only have one USB port available. Can I use an external USB Hub to add additional USB ports?
If you are attempting to connect multiple PhoneTree units to your PC and do not have the necessary USB ports available, purchase and install a true dual (or quad) host controller card instead of using an external USB Hub. This will help to ensure each PhoneTree unit receives the correct amount of USB bandwidth. When connecting your PhoneTree hardware, please limit 1 unit per USB port and no more than 12 lines per single host controller. If you need assistance determining your PC’s current USB capabilities, please contact PhoneTree Customer Support.
