The CTI Comet USB is a Caller ID unit with USB connectivity.


It is a Caller ID device for decoding the Caller's telephone number from the telephone line and presenting it on a virtual COM Port of a PC. This product is powered entirely from the USB port. This is a hardware only product and can be used with your existing software to create a fully integrated call management solution.



The CTI Comet USB has many applications. Below are some examples:

  • EPOS terminals in fast food outlets
  • Customer verification for taxi companies
  • Doctors and Dental surgeries
  • Incoming call Logging

Advisory Recommendation: Disable USB Root Hub Power Saving

The Comet derives its power from the USB connection. Users may experience problems with the operation of the Comet if the PC or Epos Terminal to which it is connected is allowed to turn off the USB Root Hub and hence switch off the Comet.


It is strongly recommended that the Power Management for the USB Root Hub is disabled.
