the console used to work until the device didn't respond again.
Ok, so chances are good that the cable is ok.
Removing the EMMC was a guess then ?
The '6100' is like a PC : removing a drive won't stop the system from booting. You need the console access to select from what device : an EMMC, or some SSD drive or even a USB key drive. Whatever happens with these "drives", the console will give output.

the computer can detect the COM port but still not be functional?
On the computer side, the USB plug, and the USB chip build into the cable, will power up, and communicate with the USB host (the USB circuitry build in the PC) so the 'PC' knows that an USB device is present, and with the help of the 'ID' of the USB cable chip, it will know what kind of driver it needs. In this case : a serial connection driver, also known as a 'COM' port (in the PC world) type of device. The serial connection itself, 3 wires, a common ground, a transmit and receive line, can not be auto detected like what you see if something is "plug and play". A serial connection is something from te past century.
So plugin in the cable makes the COM port avaible to the PC, but won't tell you anything about the presence of a connection = the receive line going up and down in a fixed frequency (115000 hz - you checked this bit rate of you port ? ) so a serial connection is establish.
That's also you final test : on the console port, if you can find these 'TX' and RX' traces, locate the TX line.
If you see the TX line go up and down frequently (shortly) after power up, you know the 6100 BIOS is outputting text. If it stays silent ........
