Anyone ever used a USB-to-Serial cable that worked out of the box? If so where did you get it?

If the issue is not the STB, then it's the computer + USB adaptor + null cable. and the procedure tests exactly this.

This procedure refers to a loading setup using a PC serial COM (including a COM port implemented with a USB to serial COM adaptor) port connected to the STB via a null modem cable with female DB-9 connectors.

Below is a step by step procedure for testing the communication link - setup and hardware - including the PC and the cable, up to the STB serial connector.
The procedure is based on what is called a loop-back test,meaning that thedata signals transmitted by the PC COM port are returned to the same port, as received data signals, by means of a wire jumper at the end of the serial data cable.
