Hi,
I have bought a USB to OBD2 cable (cheep chines thing)

My system is:
Kubuntu 22.04.1 LTS
5.15.0-47-generic
x86_64 x86_64 GNU/Linux

In OBD Auto Doctor the cable works :
-OBD Auto Doctor-
ELM327 v1.5 ISO 9141-2

But in Savvycan it gives me following :
SavvyCAN
$ sudo ./SavvyCAN-305dafd-x86_64.AppImage

-connection settings-
-add New device connection-
it finds the usb and say its a GVRET
GVRET - ttyUSB0 - 2 busses - not connected

in console:

Failed to connect to GVRET at that com port

Trying Standard Serial Mode

That device will never work with SavvyCan, BUT it will work with any ELM327 compatible app like Torque Pro or OBDFusion.
