Hi all, i recently ditched horrible slow vista on my ancient laptop for linux, making my fossilised dell perform like it's on crack.
Trouble is i can't get guzzidiag to connect anymore, the com port is blank and greyed out.
Any help will be much appreciated.
Thanks.

First thing to do is open a terminal window. Ways to do this vary by which type of desktop you have, but you can usually right-click on the desktop and the menu will have a Terminal or Open-In-Terminal selection. Alternatively, type CTRL-ALT-T and a terminal will open.

You will get something that looks like this:

[You must be registered and logged in to see this image.]


Plug in the GuzziDiag cable to a USB port. In the terminal, type:

sudo usermod -a -G dialout [enter]

You will be asked for your password. Enter your password and hit [enter].

Then, type:

ls -al /dev/ttyUSB0

You should get something like this:


[You must be registered and logged in to see this image.]




That should do it. You should now be able to connect.



cheers

Hi beetle, still greyed out sadly. I'll do a fresh install tomorrow and try again, i've been messing about in the terminal previously and fear i cocked something up trying to get it to work.
Thanks for your reply, much appreciated.

Don't reload. Try this:

With the cable plugged in and powered, check that you have this device:  /dev/tts/USB0

If so, In a terminal, run this command:

sudo chmod 666 /dev/tts/USB0

Create a symlink:

sudo ln -s /dev/tts/USB0 /dev/ttyUSB0



You might also try running GuzziDiag as root.

It comes up with 'bash: /dev/tts/USB0: No such file or directory'. So looks like something's missing.
I'll do a search and see what i need.

Try replacing the zero in the USB string with other numbers. Sometimes there is an apparent conflict between real and virtual USBs. Then again, I may be talking shyte...

Does /dev/ttyUSB0 exist when the cable is plugged in and powered?

No, I'm presuming that line should be entered in the terminal, same as the rest? It's really bugging me now, still, there's scan m5x i can fall back on for tps reset. I won't give up on this though...
Thanks again.

In a terminal, what is the output of:

ls -al /dev/*USB*


(With the cable plugged in and powered).

Something appeared!  'crw-rw---- 1 root dialout 188, 0 may  5 13.05 /dev/ttyUSB0'

And as superuser (lol !) 'lrwxrwxrwx 1 root 13 may 5 13.46 /dev/ttyUSB0 -> /dev/tts/USB0'

Did you do:

sudo usermod -a -G dialout $USER

...where $USER is your username?

So in the end i just did

sudo usermod -a -G dialout $USER


ls -al /dev/ttyUSB0.

Just adding my name did it.
Thanks again Mark, you saved what's left of my sanity

Same problem, tried all of the above, rebooted but cant get a connection. Its fine from a laptop running windoze 10, but I would prefer to use a old laptop that has linux on it out in the garage. Any more ideas besides chucking the laptop in a skip? Question

No skippy. Linux good.

What happens when you run GuzziDiag as root? Or, if you have a swot version if Linux that doesn't allow you superpowers, run it with sudo?

Thanks Beetle, one laptop saved from the skip.  Ran it with sudo, works fine.
Its a long time since I played with Linux, got to get the rapidly diminishing little grey cells working again.
