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.
The extension cable has four contacts. If it didn't, the dongle simply
wouldn't work at all.
