I still don't understand why using the extension cable makes a
difference.

If I were to take a guess...
Being serial data, vs. parallel, the port/devices only needs two
connections i.e. |..| to pass data and cables will tend to provide only
this. If the device requires the second pair i.e. |||| used typically for
power and such, to reactivate then the extension cable, if missing these
inner two wires, would not pass any charge and/or data. The device then
does not know to reactivate.
look on the inside of the ends of the extension cable and see if you can
see four contact leads and this should tell if you have all four or just
two contact leads for data only function.
Just a wag.
