[chirp_users] Chirp no work - on Windows, try Linux if possible

In Windows, after connecting the cable (no radio needed on the other
end, nor Chirp running.)
Go into the Device Manager, and look for the COM/Serial port device lists.
If there are no Yellow Triangle signs, and you only see one COM port,
that is the one you tell Chirp about.
If you see more than one, with that display on screen, unplug the cable,
wait, and re-plug it, and you'll see the list update so you can identify
which COM port to use.
If however, the one for your cable has a Yellow triangle, with a ! in
the middle, then Windows as no driver for it, because it's recognised as
either a counterfeit USB/Serial chip, or it's an old version of a
Genuine chip (not uncommon sadly with Prolific chipsets) or a chipset
that Windows does not know about (SiLab's and others typically, if so go
to their website and pull the driver you need, for your version of
Windows, and install it.)
You can either rollback the driver, and install an earlier one. Under
Win7 as you no longer receive updates, that should stick, but in effect
your are then part of the problem stealing someone else's intellectual
property by proxy. (Prolific's design and firmware.)
On Win10, you will probably have to block updates else it will update to
the current version that will again reject old/counterfeit devices, but
in these troubled times, it is not a good idea to skip security updates.
Just get a genuine FTDI or whoever's chipset based cable. OK, it costs
more, but you don't need to block security updates and compromise your
PC to keep using it.
In Linux, the Kernel has all the drivers built in, and (usually, but for
how long no one seems to say) they still work with the fake and old
version chips too. (And very well too, it has to be said.)
But... Your username must (On Debian based systems such as Ubuntu,
Mint, Raspian and so on) be a member of the "dialout" group, or you will
never get to use it. (Fedora bases systems I think have a similar
requirement, but I don't know the incantation for them.)
Open a command line window (Ctrl + Alt + T) and enter this:-
sudo aduser $USER dialout
You will be asked for your password (the same one you logged in with.
'$USER' is a system variable containing your present login name.)
After that you *MUST* Logout, and Log back In again (or reboot, if that
is easier) for the change to take effect.
Then you can use serial I/O devices.
To find out what /dev/ttyUSB* number it has been assigned. Immediately
after connecting the cable (again, no radio needed) in a command line
window, use the command
That will show you all the USB/Serial devices it knows are connected.
If you have several, compare the list without the programming cable, and
with it connected, so you can identify which device name you tell Chirp
Note! In the presence of multiple USB/Serial devices, it is common for
them to be "enumerated" (discovered) in a different order* when the
machine is next restarted, so it is usually best to confirm what you
have before starting the software!
(* There are ways to make things consistent and stable, but that is
beyond the scope of this email for now. If you are curious, look up
'udev rules' )
You may be able to "test" the cable, by connecting the apropriate pins
of the radio end of the cable together, forming a serial loop-back, then
you can use a terminal program (CuteCom for example, will need to
install that if not already present) to type to yourself. See your
radio's manual to identify which pins or terminals of the cable end to
Hope the above is not too much to digest.
